我遇到了一个无法解决的问题，当我离开我的应用程序时，我的应用程序的广播接收器继续运行。我必须手动强制停止应用程序，而我已关闭; 谢谢您的帮助。这是我的清单和我的接收器：

和myreceiver：
public class MyReceiver extends BroadcastReceiver {
public MyReceiver() {
}
public int lock = 0;
@Override
public void onReceive(Context context, Intent intent) {
Bundle extra = intent.getExtras();
if (extra != null) {
Object[] pdus = (Object[]) extra.get("pdus");
final SmsMessage[] messages = new SmsMessage[pdus.length];
for (int i = 0; i < pdus.length; i++) {
messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]);
}
if (messages.length > -1) {
for (int i = 0; i < messages.length; i++) {
String messageBody = messages[i].getMessageBody();
String phoneNumber = messages[i].getDisplayOriginatingAddress();
Toast.makeText(context, "Expéditeur:" + "\n" + phoneNumber, Toast.LENGTH_LONG).show();
Toast.makeText(context, "Message : " + "\n" + messageBody, Toast.LENGTH_LONG).show();
if (messageBody.equals("CS")) {
lock = 1;
SharedPreferences sharedPreferences = context.getSharedPreferences("appSharedPreferences", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("lockphone", phoneNumber);
editor.putInt("locksecurity", lock);
editor.commit();
Toast.makeText(context, "Association réussie !", Toast.LENGTH_LONG).show();
Toast.makeText(context, "L'option Connexion GSM est maintenant désactivée.", Toast.LENGTH_LONG).show();
}
/** else {
Toast.makeText(context, "Echec de l'association !", Toast.LENGTH_LONG).show();
Toast.makeText(context, "Merci de renseigner un numéro correct", Toast.LENGTH_LONG).show();
} **/
}
}
}
}
}

您在清单中注册了MyReceiver。因此，它被设置为始终接收广播。
如果您只想在某些时间接收广播，请：
对某些registerReceiver()使用unregisterReceiver()和Context，从清单中删除<receiver>元素，或
使用PackageManager和setComponentEnabledSetting()根据需要启用或停用<receiver>
作为前者的一个例子，this sample app有一个片段，在ACTION_BATTERY_CHANGED中注册onResume()，在onPause()注册：

else {

}
break;

};
}
因此，只有从输入角度看片段处于前台时，它才会收到该广播。
