Android TV Launcher開源項目

這個項目是機頂盒桌面，用來播放視頻、顯示圖片、利用管理和其他針對機頂盒產品的設置。目前git和CSDN code上面都沒有類似的開源項目，正好本人最近在開發類似產品，網上類似研究還非常少，完全自己實現還是比較困難。所以就把目前的項目開源出來，也有益于其他人少走彎路。
git項目地址
CSDN code項目地址

項目框架結構

Launcher項目結構
UI、adapter、實體類、圖片cache、網絡層。
這個層級關系還是和大部份項目是類似的。

功能模塊的詳細實現方式

這個部份主要講1下機頂盒Launcher實現的幾個難點，如還有其他問題請留言。

app管理

1.掃描可啟動的利用

這里寫圖片描述
由于原項目效果圖不符合開源要求所以去掉了。

    public ArrayList<AppBean> getLaunchAppList() {
        PackageManager localPackageManager = mContext.getPackageManager();
        Intent localIntent = new Intent("android.intent.action.MAIN");
        localIntent.addCategory("android.intent.category.LAUNCHER");
        List<ResolveInfo> localList = localPackageManager.queryIntentActivities(localIntent, 0);
        ArrayList<AppBean> localArrayList = null;
        Iterator<ResolveInfo> localIterator = null;
        if (localList != null) {
            localArrayList = new ArrayList<AppBean>();
            localIterator = localList.iterator();
        }
        while (true) {
            if (!localIterator.hasNext())
                break;
            ResolveInfo localResolveInfo = (ResolveInfo) localIterator.next();
            AppBean localAppBean = new AppBean();
            localAppBean.setIcon(localResolveInfo.activityInfo.loadIcon(localPackageManager));
            localAppBean.setName(localResolveInfo.activityInfo.loadLabel(localPackageManager).toString());
            localAppBean.setPackageName(localResolveInfo.activityInfo.packageName);
            localAppBean.setDataDir(localResolveInfo.activityInfo.applicationInfo.publicSourceDir);
            localAppBean.setLauncherName(localResolveInfo.activityInfo.name);
            String pkgName = localResolveInfo.activityInfo.packageName;
            PackageInfo mPackageInfo;
            try {
                mPackageInfo = mContext.getPackageManager().getPackageInfo(pkgName, 0);
                if ((mPackageInfo.applicationInfo.flags & mPackageInfo.applicationInfo.FLAG_SYSTEM) > 0) {//系統預裝
                    localAppBean.setSysApp(true);
                }
            } catch (NameNotFoundException e) {
                e.printStackTrace();
            }

            String noSeeApk = localAppBean.getPackageName();

            // 屏蔽1些apk
            if (!noSeeApk.equals("com.cqsmiletv") && !noSeeApk.endsWith("com.starcor.hunan") && !noSeeApk.endsWith("com.tcl.matrix.tventrance")) {
                localArrayList.add(localAppBean);
            }
        }
        return localArrayList;
    }

 //接收安裝廣播
            if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) {

                String packageName = intent.getDataString();
                List<ResolveInfo> list = Tools.findActivitiesForPackage(context, packageName);
                ResolveInfo info = list.get(0);
                PackageManager localPackageManager = context.getPackageManager();
                AppBean localAppBean = new AppBean();
                localAppBean.setIcon(info.activityInfo.loadIcon(localPackageManager));
                localAppBean.setName(info.activityInfo.loadLabel(localPackageManager).toString());
                localAppBean.setPackageName(info.activityInfo.packageName);
                localAppBean.setDataDir(info.activityInfo.applicationInfo.publicSourceDir);

                mAppList.add(localAppBean);
            }

上面的第1個代碼模塊主要是掃描機頂盒上面安裝了哪些利用，把信息填到實體類里面去，還可以根據自己產品要求屏蔽1些apk。
第2個代碼塊是檢測安裝廣播，根據需要更新數據。

2.掃描可卸載的利用

這里寫圖片描述

    public ArrayList<AppBean> getUninstallAppList() {
        PackageManager localPackageManager = mContext.getPackageManager();
        Intent localIntent = new Intent("android.intent.action.MAIN");
        localIntent.addCategory("android.intent.category.LAUNCHER");
        List<ResolveInfo> localList = localPackageManager.queryIntentActivities(localIntent, 0);
        ArrayList<AppBean> localArrayList = null;
        Iterator<ResolveInfo> localIterator = null;
        if (localList != null) {
            localArrayList = new ArrayList<AppBean>();
            localIterator = localList.iterator();
        }
        while (true) {
            if (!localIterator.hasNext())
                break;
            ResolveInfo localResolveInfo = (ResolveInfo) localIterator.next();
            AppBean localAppBean = new AppBean();
            localAppBean.setIcon(localResolveInfo.activityInfo.loadIcon(localPackageManager));
            localAppBean.setName(localResolveInfo.activityInfo.loadLabel(localPackageManager).toString());
            localAppBean.setPackageName(localResolveInfo.activityInfo.packageName);
            localAppBean.setDataDir(localResolveInfo.activityInfo.applicationInfo.publicSourceDir);
            String pkgName = localResolveInfo.activityInfo.packageName;
            PackageInfo mPackageInfo;
            try {
                mPackageInfo = mContext.getPackageManager().getPackageInfo(pkgName, 0);
                if ((mPackageInfo.applicationInfo.flags & mPackageInfo.applicationInfo.FLAG_SYSTEM) > 0) {//系統預裝
                    localAppBean.setSysApp(true);
                } else {
                    localArrayList.add(localAppBean);
                }
            } catch (NameNotFoundException e) {
                e.printStackTrace();
            }
        }
        return localArrayList;
    }

//接收卸載廣播
            if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) {
                String receiverName = intent.getDataString();
                receiverName = receiverName.substring(8);
                AppBean appBean;
                for(int i=0;i<mAppList.size();i++){
                    appBean = mAppList.get(i);
                   String packageName = appBean.getPackageName();
                    if(packageName.equals(receiverName)){
                        mAppList.remove(i);
                        adapter.notifyDataSetChanged();
                    }
                }
            }

由于系統預裝的按常理方法是沒法卸載的，應當屏蔽掉。卸載的時候根據廣播返回標志更新數據。

3.自啟動管理

這里寫圖片描述

    public ArrayList<AppBean> getAutoRunAppList() {
        PackageManager localPackageManager = mContext.getPackageManager();
        Intent localIntent = new Intent("android.intent.action.MAIN");
        localIntent.addCategory("android.intent.category.LAUNCHER");
        List<ResolveInfo> localList = localPackageManager.queryIntentActivities(localIntent, 0);
        ArrayList<AppBean> localArrayList = null;
        Iterator<ResolveInfo> localIterator = null;
        if (localList != null) {
            localArrayList = new ArrayList<AppBean>();
            localIterator = localList.iterator();
        }

        while (true) {
            if (!localIterator.hasNext())
                break;
            ResolveInfo localResolveInfo = localIterator.next();
            AppBean localAppBean = new AppBean();
            localAppBean.setIcon(localResolveInfo.activityInfo.loadIcon(localPackageManager));
            localAppBean.setName(localResolveInfo.activityInfo.loadLabel(localPackageManager).toString());
            localAppBean.setPackageName(localResolveInfo.activityInfo.packageName);
            localAppBean.setDataDir(localResolveInfo.activityInfo.applicationInfo.publicSourceDir);
            String pkgName = localResolveInfo.activityInfo.packageName;
            String permission = "android.permission.RECEIVE_BOOT_COMPLETED";
            try {
                PackageInfo mPackageInfo = mContext.getPackageManager().getPackageInfo(pkgName, 0);
                if ((PackageManager.PERMISSION_GRANTED == localPackageManager.checkPermission(permission, pkgName)) && !((mPackageInfo.applicationInfo.flags & mPackageInfo.applicationInfo.FLAG_SYSTEM) > 0)) {
                    localArrayList.add(localAppBean);
                }
            } catch (NameNotFoundException e) {
                e.printStackTrace();
            }
        }
        return localArrayList;
    }

掃描利用權限查看是不是是自啟動app，返回所有自啟動app。

    public boolean manageBoot(String pkg,boolean able) {
        Process process = null;
        DataOutputStream dos = null;
        String command = null;
        try {
            process = Runtime.getRuntime().exec("su");
            dos = new DataOutputStream(process.getOutputStream());
            dos.flush();
            command = "export LD_LIBRARY_PATH=/vendor/lib:/system/lib  
";
            dos.writeBytes(command);
            //(有些cls含有$，需要處理1下，不然會制止失敗，比如微信)
            //但是獲得利用是不是允許或制止開機啟動的時候就不用途理cls，否則得不到狀態值
           //            cls = cls.replace("$", "$");
           //            command = "pm disable " + pkg + "/" + cls + " 
";
            if(able){
                command = "pm enable " + pkg;
            }else{
                command = "pm disable " + pkg;
            }
            dos.writeBytes(command);
            dos.writeBytes("exit " + "
");
            dos.flush();
            try {
                process.waitFor();
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            int exitValue = process.exitValue();
            try {
                if (exitValue == 0) {
                    return true;
                } else {
                    return false;
                }
            } catch (Exception e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (dos != null) {
                try {
                    dos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
            if (process != null) {
                process.destroy();
            }
        }
        return false;
    }

制止利用自啟動，需要有root權限。

網絡設置

1.WiFi

掃描附近WiFi

這里寫圖片描述

public void StartScan() {
        mWifiManager.startScan();
        // 得到掃描結果
        mWifiList = mWifiManager.getScanResults();
        // 得到配置好的網絡連接
        mWifiConfigurations = mWifiManager.getConfiguredNetworks();
        Log.v("mWifiManager", mWifiManager+"");
        Log.v("mWifiList", mWifiList+"");
        Log.v("mWifiConfigurations", mWifiConfigurations+"");
    }

根據WiFi幾種加密方式配置wificonfiguration

public WifiConfiguration CreatConfiguration(String SSID, String Password,
            int Type) {
        WifiConfiguration configuration = new WifiConfiguration();
        configuration.allowedAuthAlgorithms.clear();
        configuration.allowedGroupCiphers.clear();
        configuration.allowedKeyManagement.clear();
        configuration.allowedPairwiseCiphers.clear();
        configuration.allowedProtocols.clear();
        configuration.SSID = """ + SSID + """;
        WifiConfiguration tempConfiguration = IsExits(SSID, mWifiManager);
        if (tempConfiguration != null) {
            mWifiManager.removeNetwork(tempConfiguration.networkId);
        }
        // WIFICIPHER_NOPASS
        if (Type == 1) {
            configuration.wepKeys[0] = "";
            configuration.allowedKeyManagement
                    .set(WifiConfiguration.KeyMgmt.NONE);
            configuration.wepTxKeyIndex = 0;
        }
        // WIFICIPHER_WEP
        if (Type == 2) {
            configuration.hiddenSSID = true;
            configuration.wepKeys[0] = """ + Password + """;
            configuration.allowedAuthAlgorithms
                    .set(WifiConfiguration.AuthAlgorithm.SHARED);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.CCMP);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.TKIP);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.WEP40);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.WEP104);
            configuration.allowedKeyManagement
                    .set(WifiConfiguration.KeyMgmt.NONE);
            configuration.wepTxKeyIndex = 0;
        }
        // WIFICIPHER_WPA
        if (Type == 3) {
            configuration.preSharedKey = """ + Password + """;
            configuration.hiddenSSID = true;
            configuration.allowedAuthAlgorithms
                    .set(WifiConfiguration.AuthAlgorithm.OPEN);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.TKIP);
            configuration.allowedKeyManagement
                    .set(WifiConfiguration.KeyMgmt.WPA_PSK);
            configuration.allowedPairwiseCiphers
                    .set(WifiConfiguration.PairwiseCipher.TKIP);
            configuration.allowedGroupCiphers
                    .set(WifiConfiguration.GroupCipher.CCMP);
            configuration.allowedPairwiseCiphers
                    .set(WifiConfiguration.PairwiseCipher.CCMP);
            configuration.status = WifiConfiguration.Status.ENABLED;
        }
        return configuration;
    }

根據上面得到的信息用WiFimanager連接網絡，返回的信息可判斷是不是連接成功。

public int AddNetwork(WifiConfiguration configuration) {
        int configurationId = mWifiManager.addNetwork(configuration);
        boolean b = mWifiManager.enableNetwork(configurationId, true);
        return configurationId;
    }

2.藍牙

這里寫圖片描述

在機頂盒中藍牙經常使用于藍牙遙控、鍵盤、游戲手柄。
注冊藍牙狀態廣播（連接、正在連接、已連接）

        IntentFilter intent = new IntentFilter();
        // 用BroadcastReceiver來獲得搜索結果
        intent.addAction(BluetoothDevice.ACTION_FOUND);
        //每當掃描模式變化的時候，利用程序可以為通過ACTION_SCAN_MODE_CHANGED值來監聽全局的消息通知。
        // 比如，當裝備停止被搜索以后，該消息可以被系統通知     
 生活不易，碼農辛苦
