[英]SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.BATTERY_CHANGED
[英]Permission Denial: not allowed to send broadcast android.intent.action.AIRPLANE_MODE
我正在尝试以编程方式设置飞行模式。
Settings.System.putInt(context.getContentResolver(), Settings.Global.AIRPLANE_MODE_ON, 1);
Intent aeroPlaneIntent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
aeroPlaneIntent.putExtra("state", true);
context.sendBroadcast(aeroPlaneIntent);
设置 Global.AIRPLANE_MODE_ON 失败,就好像我检查它返回 0 (OFF) 的状态
尝试广播它会引发以下异常的意图:

有没有办法设置飞行模式开/关? 请帮忙
以下内容已在 Android API 23 和 26 模拟器上进行了测试和验证;
所需的清单权限如下;
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" tools:ignore="ProtectedPermissions"/>
代码如下;
boolean turnOnOffAirplaneMode(boolean isTurnOn) {
boolean result = true;
try {
Settings.Global.putInt(context.getContentResolver(),
Settings.Global.AIRPLANE_MODE_ON, isTurnOn ? 1 : 0);
// The below old code is now not necessary @ API Level 23, 26 ...
//Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
//context.sendBroadcast(intent);
} catch (Exception e) {
result = false;
}
return result;
}
APK 应使用相关平台密钥进行签名,以便上述工作。 在模拟器测试中,APK 使用 Google Sign Keys 进行签名。 密钥取决于设备的 OEM。
$ adb shell
$ su
# settings put global airplane_mode_on 0
# am broadcast -a android.intent.action.AIRPLANE_MODE --ez state false
