android - 通知はエミュレーターでは機能しますが、電話では機能しません

Question

これは単純なアプリで、ユーザーから 2 つのテキスト入力を受け取り、ボタンをクリックすると通知を作成します。コードは次のとおりです。

package com.dewey.notifymanager;

import android.os.Bundle;
import android.app.Activity;
import android.app.Notification;
import android.app.NotificationManager;
import android.content.Context;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final Button button = (Button) findViewById(R.id.button1);
        final TextView texty = (TextView) findViewById(R.id.textView2);
        final EditText input = (EditText) findViewById(R.id.editText1);
        final EditText input2 = (EditText) findViewById(R.id.editText2);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                String notificationmessage = input.getText().toString();
                String notificationdetails = input2.getText().toString();
                texty.setText("Notification Created");
                displayNotification(notificationmessage, notificationdetails);
            }
        });
    }
    @Override
    protected void onStart() {

    super.onStart();


    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }



    public void displayNotification(String msg,String details)
    {
    NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    Notification notification = new Notification(R.drawable.ic_launcher, msg, System.currentTimeMillis());




    notification.setLatestEventInfo(this, msg, details, null);
    int num = 0;
    manager.notify(num, notification);

    }

}

アプリはエミュレーターで動作し、通知を表示します。

しかし、電話で実行すると、ボタンをクリックしても通知が表示されず、Android 2.3 を実行している電話で実行すると、アプリがクラッシュし、ボタンをクリックすると予期せず停止します。

ログキャットは次のとおりです。

私のマニフェストに問題がありますか?:

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="15" />

<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name=".MainActivity"
        android:label="@string/title_activity_main" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

アプリケーションは、setLatestEventInfo（）に必要なPendingIntentを設定する必要があります。したがって、置き換えます：

notification.setLatestEventInfo(this, msg, details, null);

と

Intent intent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, msg, details, pendingIntent);

これにより、アプリケーションが機能しますが、さらにApilevelを区別することを強くお勧めします。アプリケーションは次のようになります。

public class MainActivity extends Activity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final Button button = (Button) findViewById(R.id.button1);
        final TextView texty = (TextView) findViewById(R.id.textView2);
        final EditText input = (EditText) findViewById(R.id.editText1);
        final EditText input2 = (EditText) findViewById(R.id.editText2);
        button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {

                String notificationmessage = input.getText().toString();
                String notificationdetails = input2.getText().toString();
                texty.setText("Notification Created");
                displayNotification(notificationmessage, notificationdetails);
            }
        });
    }

    @Override
    protected void onStart() {
        super.onStart();
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }

    /**
     * Show a notification while this service is running.
     * 
     */
    private void displayNotification(String msg, String details) {
        int num = 0;
        NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        Intent intent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0,
                intent, 0);
        int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion <= 8) {
            manager.notify(num,
                    createNotificationApi8(msg, details, pendingIntent));
        } else {
            manager.notify(num,
                    createNotificationApi14(msg, details, pendingIntent));
        }
    }

    @TargetApi(value = 14)
    private Notification createNotificationApi14(String msg, String details,
            PendingIntent intent) {
        Notification.Builder builder = new Builder(getApplicationContext());
        builder.setSmallIcon(R.drawable.ic_launcher);
        builder.setContentTitle(msg);
        builder.setContentIntent(intent);
        builder.setContentInfo(details);
        Notification notification = builder.getNotification();
        return notification;
    }

    @TargetApi(value = 8)
    private Notification createNotificationApi8(String msg, String details,
            PendingIntent intent) {
        Notification notification = new Notification(R.drawable.ic_launcher,
                msg, System.currentTimeMillis());
        notification.setLatestEventInfo(this, msg, details, intent);
        return notification;
    }
}

これがお役に立てば幸いです。それ以外の場合はお知らせください。アンダック
