Android獲取USB調(diào)試狀態(tài)

獲取很簡單,適用于API 17+

      //檢查USB調(diào)試狀態(tài)
    public static boolean checkUSBDebug(){
        if(Settings.Global.getInt( Context.getContentResolver(), Settings.Global.ADB_ENABLED, 0) == 1) {
           return true;
        } else {
           return false;
        }
    }

Android打開USB調(diào)試開關(guān)

Settings.Global.putInt(Context.getContentResolver(), Settings.Global.ADB_ENABLED, 1);

需要添加權(quán)限,但是這權(quán)限僅系統(tǒng)應用有權(quán)限申請：

<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

這里有個取巧的辦法能獲取權(quán)限，安裝apk后：adb shell執(zhí)行命令：

adb -d shell pm grant pkgname android.permission.WRITE_SECURE_SETTINGS

這樣就能實現(xiàn)當USB調(diào)試開關(guān)關(guān)掉之后，apk自動判斷并且去打開了

Android打開開發(fā)者選項開關(guān)

Settings.Global.putInt(Context.getContentResolver(), Settings.Global.DEVELOPMENT_SETTINGS_ENABLED, 1);

Android獲取手機是否靜音，如果否，則設置靜音

    //判斷手機是否處于靜音狀態(tài)，如果非靜音則設置靜音
    public static void checkAudio(Context context){
        AudioManager am = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);

        switch (am.getRingerMode()) {
            case AudioManager.RINGER_MODE_SILENT:
                Log.i(TAG,"Silent mode");
                break;
            case AudioManager.RINGER_MODE_VIBRATE:
                Log.i(TAG,"Vibrate mode");
                am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                break;
            case AudioManager.RINGER_MODE_NORMAL:
                Log.i(TAG,"Normal mode");
                am.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                break;
        }
    }

Android獲取手機wifi狀態(tài)，如果關(guān)閉，則打開

    //判斷手機wifi是否掉線，如果掉線則強制重連
    public static boolean  checkWifiState(Context context){
        ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
        if (networkInfo != null && networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
            return true;
        }
        //打開wifi
        WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);
        wifiManager.setWifiEnabled(true);
        return false;
    }

需要申請權(quán)限：

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
