android 6.0擷取 WRITE_SETTINGS 許可權

標籤：

android 6.0上唯寫在AndroidManifest中是不行的，還必須手動開啟才行

    private void setBrightnessMode(Context context, int mode) {        try {            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {                if (Settings.System.canWrite(context)) {                    Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, mode);                } else {                    Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_WRITE_SETTINGS);                    intent.setData(Uri.parse("package:" + context.getPackageName()));                    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);                    context.startActivity(intent);                }            } else {                Settings.System.putInt(context.getContentResolver(), Settings.System.SCREEN_BRIGHTNESS_MODE, mode);            }        } catch (Exception e) {            e.printStackTrace();        }    }
