Question

我已注册此广播接收器

public class NotifyAlarmBroadcast extends BroadcastReceiver{
    public Context context;
    public static final String NOTI = "android.intent.action.MAIN";
// actually i want NOTI = "com.sumit.timekeeper.NotifyAlarm"
// this too is not working
// help me here please

@Override
public void onReceive(Context _context, Intent intent) {
    context = _context;
    Uri data = intent.getData();
    String reason = intent.getStringExtra("alarm_reason");
    Intent intentalarm = new Intent(NOTI, data);

    intentalarm.putExtra("reason", reason);
    context.startActivity(intentalarm);
}

}

和清单

<application android:icon="@drawable/icon" android:label="@string/app_name">
    <activity android:name=".TimeKeeperStartActivity"
        android:screenOrientation="portrait" android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

    <activity android:name=".NotifyAlarm"
        android:screenOrientation="portrait" android:theme="@android:style/Theme.Dialog">
        <intent-filter>
            <action android:name="com.sumit.timekeeper.NotifyAlarm">
            </action>
        </intent-filter>
    </activity>

    <receiver android:name=".NotifyAlarmBroadcast">
        <intent-filter>
            <action android:name="com.sumit.timekeeper.NotifyAlarmBroadcast" />
        </intent-filter>
    </receiver>
</application>

但当行到达context.startActivity（intentalarm）; 应用程序崩溃

可能是我们将第一个参数传递给Intent的地方，我不清楚请帮帮我。

尝试在意图中添加FLAG_ACTIVITY_NEW_TASK标记。

intentalarm.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Android：为什么BroadcastReceiver会崩溃？
