显示电池电量不足警告时，BroadcastReceiverBATTERY_LOW崩溃

我通过意图过滤器BroadcastReceiver和BATTERY_LOW拥有电池BATTERY_OKAY，此接收器正常工作，但是当显示电池电量不足警告（电池百分比低于15％）时，此日志导致应用程序崩溃：

  

12-18 03：13：49.651 1802-1802 / E / Android运行时：致命异常：主要
                                                                                          程序：，PID：1802
                                                                                          java.lang.RuntimeException：无法实例化接收方的接收方。BatteryLevelReceiver：java.lang.ClassnotFoundException：在路径：DexPathList [[zip文件“ /data/app/-1.apk””上找不到类“ receivers.BatteryLevelReceiver”，压缩文件“ /data/data//code_cache/secondary-dexes/-1.apk.classes2.zip”，压缩文件...

BatteryLevelReceiver ：

public class BatteryLevelReceiver extends BroadcastReceiver {
private static final String TAG = BatteryLevelReceiver.class.getSimpleName();
@Override
public void onReceive(Context context,Intent intent) {
try {
int curentPercent = getBatteryPercentage(context);
Log.e(TAG,"getBatteryPercentage: " + curentPercent);
} catch (Exception e){
e.printStackTrace();
}
}
public static int getBatteryPercentage(Context context) {
try {
if (Build.VERSION.SDK_INT >= 21) {
BatteryManager bm = (BatteryManager) context.getSystemService(Context.BATTERY_SERVICE);
return bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);
} else {
IntentFilter iFilter = new IntentFilter(Intent.actION_BATTERY_CHANGED);
Intent batteryStatus = context.registerReceiver(null,iFilter);
int level = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL,-1) : -1;
int scale = batteryStatus != null ? batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE,-1) : -1;
double batteryPct = level / (double) scale;
return (int) (batteryPct * 100);
}
}catch(Exception e) {
e.printStackTrace();
Log.e(TAG,"getBatteryPercentage: ");
}
return 1111;
}
}


AndroidManifest ：

android:allowBackup="true"
android:icon="@mipmap/ic_logo"
android:label="@string/app_name"

应用程序类：

public class AppController extends MultiDexApplication {
...
@Override
public void onCreate() {
super.onCreate();
MultiDex.install(this);
}
@Override
public void onconfigurationChanged(Configuration newConfig) {
super.onconfigurationChanged(newConfig);

我将意图动作从LOW更改为CHANGED，但问题没有解决。

您正在尝试在广播接收器中注册广播接收器，

删除
Intent batteryStatus = context.registerReceiver(null,iFilter);

在“活动/片段”中注册您的服务

如果要发送广播，应该致电context.sendBroadcast
