清单：

 <application

  <meta-data
            android:name="AA_DB_NAME"
            android:value="appdb" />
        <meta-data
            android:name="AA_DB_VERSION"
            android:value="1" />

  </application>

Application.java：

public class Application extends android.app.Application {

  public Application() {

  }

  @Override
  public void onCreate() {
    super.onCreate();

    // Initialize the Parse SDK.

    Parse.initialize(this, "", "");

    PushService.setDefaultPushCallback(this, MainActivity.class);

    ParseInstallation.getCurrentInstallation().saveInBackground();


  }
}

的build.gradle：

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.0.+'
    compile files('libs/Parse-1.9.3.jar')
    compile files('libs/bolts-android-1.2.0.jar')
    compile files('libs/activeandroid-3.0.jar')     

}

我不知道为什么它在kitkat版本中工作而不是在棒棒糖版本中。我已经将appcompat lib更新为22.但是在运行时仍然发生错误。任何人都可以帮助我。谢谢。

我遇到了同样的问题。但我下载测试版并构建它。一切都很好。从here下载测试版3.1。

Answer 2

检查您之前是否在Lollipop上安装了应用程序，因此您必须在assetets中使用migration .sql文件或删除设备上的所有应用程序数据，然后安装新的应用程序版本。
