[英]Broadcast receiver not working when application close from task manager in lollipop
我创建广播接收器来接收短信。 它仅在打开应用程序时有效。 当我们从任务管理器中删除应用程序时,它将无法正常工作。 它可以在软糖,奇巧中使用,但在棒棒糖版本中则不能使用。
public class MobiricReceiver extends BroadcastReceiver {
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
public void onReceive(Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);
// Show Alert
int duration = Toast.LENGTH_LONG;
Toast toast = Toast.makeText(context,
"senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
} // end for loop
} // bundle is null
} catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}
}

这是非常简单的解决方案。在Menifest->活动标签中添加它
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:screenOrientation="portrait"
android:autoRemoveFromRecents="true">
</activity>
在后退按钮上,请使用此代码完成活动
if(android.os.Build.VERSION.SDK_INT >= 21)
{
getActivity().finishAndRemoveTask();
}
else
{
getActivity().finish();
}
