[英]NoClassDefFoundError: com.google.android.gms.common.GooglePlayServicesUtil on device
[英]getting error java.lang.NoClassDefFoundError: com.google.android.gms.common.GooglePlayServicesUtil
我知道已经有很多这样的问题,我已经阅读了所有问题,但仍然找不到解决方案。 我做了什么:
我从http://developer.android.com/google/play-services/setup.html#Install安装了Google Play sdk后,所有步骤都很好,在Android选项卡中的项目属性中,我有“ Google Play服务库”,在Java Builder路径中:“ Android私有库”我有google-play-service.jar,并且已选择此库。 我也做了Import lib project。
我从http://developer.android.com/google/gcm/client.html获取的测试代码。 我的清单文件:

我的Java代码:包lt.vaziouju.vaziuoju;

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;
}
}
如果您有任何想法,我将不胜感激。 我知道我在android编程上还不够好,刚刚开始学习GCM,但是我已经花了6个小时来阅读Google,什么也没有。
感谢您的任何想法。
您正在使用Eclipse吗? 如果Eclipse看到要编译的jar文件,则不一定将其包含在apk中。 (您必须在几个地方提到这个罐子,通常人们不记得在几个地方。)
右键单击项目名称-构建路径-配置构建路径-订购并导出。
同一对话框中有一个“项目”选项卡,您可以在其中指定所依赖的项目。
如果这样不起作用,请将jar放入项目的libs子目录中。
