每当手机插上电源时,我都会激活我的应用程序。 这是我的清单
<receiver android:name=".PowerConnectionReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>
</intent-filter>
</receiver>
这是我的广播接收器
@Override
public void onReceive(Context context, Intent intent) {
Log.w("TAG", "Just received connection broadcast");
IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null, ifilter); //this line is causing the crash
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, 0);
现在,导致朋友手机崩溃的线路(我的一切工作正常)是这个
Intent batteryStatus = context.registerReceiver(null, ifilter);
有人可以告诉我是什么原因以及如何解决? 我的手机是与最新的Android JB的Galaxy nexus,他的手机是LG optimus与姜饼的一个
这是logcat

答案 0 :(得分:5)
您收到ReceiverCallNotAllowedException
。
当
registerReceiver(BroadcastReceiver, IntentFilter)
和bindService(Intent, ServiceConnection, int)
时,会抛出此异常 这些方法正在从BroadcastReceiver组件中使用。在 在这种情况下,组件将在返回时不再处于活动状态 接收Intent,因此使用异步API无效。
这意味着,您无法在<{1}}内注册<{1}} 。
修改强>
BroadcastReceiver的工作示例,它侦听BroadcastReceiver
Intent:
BroadcastReceiver
现在您只需致电ACTION_BATTERY_CHANGED
。
