我正在编写通知应用程序。要设置通知，我使用 AlarmManager。

一切似乎都运行良好，不幸的是在华为没有。当用户关闭应用程序通知时（在其他设备上 LG、NEXUS 都运行良好）。

知道如何解决吗？

    intent = new Intent(context, AlarmReceiver.class);
    sender = PendingIntent.getBroadcast(context, alarmId, intent, 0);


    am.set(android.app.AlarmManager.RTC_WAKEUP, timeToAlarm, sender);

编辑

public class AlarmReceiver extends BroadcastReceiver {
private static final String TAG = "AlarmReceiver";
private PowerManager.WakeLock wakeLock;

@Override
public void onReceive(Context context, Intent intent) {

    PowerManager pm = (PowerManager) context
            .getSystemService(Context.POWER_SERVICE);
    wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, TAG);

    wakeLock.acquire();

    new NotificationUtils(context, null).postNotification(context.getString(R.string.notification_title), context.getString(R.string.notification_message));

    unlock();
}

private void unlock() {
    if (wakeLock != null)
        if (wakeLock.isHeld())
            wakeLock.release();

    wakeLock = null;
}

}

在测试我的通知时找到了这个解决方案。在 OnCreate() 中编写这个调用 ifHuaweiAlert() 之后，看看会发生什么。

private void ifHuaweiAlert() {
    final SharedPreferences settings = getSharedPreferences("ProtectedApps", MODE_PRIVATE);
    final String saveIfSkip = "skipProtectedAppsMessage";
    boolean skipMessage = settings.getBoolean(saveIfSkip, false);
    if (!skipMessage) {
        final SharedPreferences.Editor editor = settings.edit();
        Intent intent = new Intent();
        intent.setClassName("com.huawei.systemmanager", "com.huawei.systemmanager.optimize.process.ProtectActivity");
        if (isCallable(intent)) {
            final AppCompatCheckBox dontShowAgain = new AppCompatCheckBox(this);
            dontShowAgain.setText("Do not show again");
            dontShowAgain.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                @Override
                public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                    editor.putBoolean(saveIfSkip, isChecked);
                    editor.apply();
                }
            });

            new AlertDialog.Builder(this)
                    .setIcon(android.R.drawable.ic_dialog_alert)
                    .setTitle(R.string.huawei_protected_apps)
                    .setMessage(String.format("%s" + " "requiers to be enabled in Protected Apps) , getString(R.string.app_name)))
                    .setView(dontShowAgain)
                    .setPositiveButton("Protected Apps", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            huaweiProtectedApps();
                        }
                    })
                    .setNegativeButton(android.R.string.cancel, null)
                    .show();
        } else {
            editor.putBoolean(saveIfSkip, true);
            editor.apply();
        }
    }
}

private boolean isCallable(Intent intent) {
    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,
            PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

private void huaweiProtectedApps() {
    try {
        String cmd = "am start -n com.huawei.systemmanager/.optimize.process.ProtectActivity";
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            cmd += " --user " + getUserSerial();
        }
        Runtime.getRuntime().exec(cmd);
    } catch (IOException ignored) {
    }
}

private String getUserSerial() {
    //noinspection ResourceType
    Object userManager = getSystemService("user");
    if (null == userManager) return "";

    try {
        Method myUserHandleMethod = android.os.Process.class.getMethod("myUserHandle", (Class<?>[]) null);
        Object myUserHandle = myUserHandleMethod.invoke(android.os.Process.class, (Object[]) null);
        Method getSerialNumberForUser = userManager.getClass().getMethod("getSerialNumberForUser", myUserHandle.getClass());
        Long userSerial = (Long) getSerialNumberForUser.invoke(userManager, myUserHandle);
        if (userSerial != null) {
            return String.valueOf(userSerial);
        } else {
            return "";
        }
    } catch (NoSuchMethodException | IllegalArgumentException | InvocationTargetException | IllegalAccessException ignored) {
    }
    return "";
}

设置中有受保护的应用程序选项。去那里并选择您的应用程序
