我知道已经有很多问题是这样的,我读了所有这些问题,但无论如何都无法找到解决方案。我做了什么:

我从http://developer.android.com/google/play-services/setup.html#Install完成了所有这些步骤以安装google play sdk 在我的项目属性Android选项卡中我有“谷歌播放服务库”确定,在Java Builder路径:“Android私人库”我有google-play-service.jar,这个库被选中。我也做了导入lib项目。

我从http://developer.android.com/google/gcm/client.html获取的测试代码。 我的清单文件:          

<uses-sdk
    android:minSdkVersion="9"
    android:targetSdkVersion="19" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.WAKE_LOCK" />

<application

    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="api key here" />

    <receiver
        android:name="lt.vaziouju.vaziuoju.GcmBroadcastReceiver"
        android:permission="lt.vaziouju.vaziuoju.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="lt.vaziouju.vaziuoju.c2dm.intent.RECEIVE" />

            <category android:name="lt.vaziouju.vaziuoju" />
        </intent-filter>
    </receiver>

    <service android:name="lt.vaziouju.vaziuoju.GcmIntentService" />

    <activity
        ...
    </activity>
</application>

我的java代码: 包lt.vaziouju.vaziuoju;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.widget.TextView;

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GooglePlayServicesUtil;


public class Test_GCM extends Activity {

private final static int PLAY_SERVICES_RESOLUTION_REQUEST = 9000;
private static final String TAG = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_test__gcm);

    TextView mDisplay = (TextView) findViewById(R.id.display);

    Context context = getApplicationContext();

    // Check device for Play Services APK.
    if (checkPlayServices()) {
        // If this check succeeds, proceed with normal processing.
        // Otherwise, prompt user to get valid Play Services APK.
    }
}

// You need to do the Play Services APK check here too.
@Override
protected void onResume() {
    super.onResume();
    checkPlayServices();
}

/**
 * Check the device to make sure it has the Google Play Services APK. If
 * it doesn't, display a dialog that allows users to download the APK from
 * the Google Play Store or enable it in the device's system settings.
 */


private boolean checkPlayServices() {
    int resultCode = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if (resultCode != ConnectionResult.SUCCESS) {
        if (GooglePlayServicesUtil.isUserRecoverableError(resultCode)) {
            GooglePlayServicesUtil.getErrorDialog(resultCode, this, PLAY_SERVICES_RESOLUTION_REQUEST).show();
        } else {
            Log.i(TAG, "This device is not supported.");
            finish();
        }
        return false;
    }
    return true;
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.test__gcm, menu);
    return true;
}

}

如果你知道我怎么做,那将是一件事。我知道我在android编程方面不够好,刚刚开始学习GCM,但我已经花了6个小时阅读谷歌,什么都没有。

感谢您的任何想法。

您使用的是Eclipse吗?如果Eclipse看到一个用于编译的jar文件,它不一定将它包含在apk中。 (你必须在几个地方提到罐子,通常人们不记得有多少个地方。)

点击项目名称 - 构建路径 - 配置构建路径 - 订单和导出。

同一个对话框有一个Projects选项卡,您可以在此处指定您所依赖的项目。

如果这不起作用,请将jar放入项目的libs子目录中。
