Question

我有一个项目，我想将Parse添加到它。我在我的电脑上安装了Parse服务器，从他们的网站下载了SDK，工作得很好但是，我不想在他们的网站上使用SDK，我只想将库添加到我的项目中。

这是我做的：我将这些库文件复制到我的项目libs文件夹

'libs/parse-android-1.13.1.jar'
'libs/bolts-android-1.2.0.jar'

这是我的代码：

build.gradle文件中的

：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'

    compile files('libs/parse-android-1.13.1.jar')
    compile files('libs/bolts-android-1.2.0.jar')

}

我添加了上面的依赖项。

主要活动：

public class MainActivity extends AppCompatActivity {

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

        Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
                .applicationId("kooora.com100plus")
                .clientKey("kooora.com100plusMasterKey")
                .server("http://10.0.2.2:1337/parse/")
                .build()
        );


        ParseObject gameScore = new ParseObject("GameScore");
        gameScore.put("score", 1337);
        gameScore.put("playerName", "Sean Plott");
        gameScore.put("cheatMode", false);
        gameScore.saveInBackground(new SaveCallback() {
            public void done(ParseException e) {
                if (e == null) {
                    Log.i("Parse", "Save Succeeded");
                } else {
                    Log.i("Parse", e.getMessage());
                }
            }
        });
    }
}

以下是我收到错误的日志：

我不知道出了什么问题！我只是得到一个运行时错误，它停止工作

更新：

正如评论中所建议的那样，我将初始化放在我的Application类中实际上我从原始SDK复制了类，但似乎这个初始化没有执行，

这是我从原始SDK中添加的类：

public class StarterApplication extends Application {

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

        // Enable Local Datastore.
        Parse.enableLocalDatastore(this);

        // Add your initialization code here
        Parse.initialize(new Parse.Configuration.Builder(getApplicationContext())
                .applicationId("kooora.com100plus")
                .clientKey("kooora.com100plusMasterKey")
                .server("http://10.0.2.2:1337/parse/")
        .build()
        );

          ParseUser.enableAutomaticUser();
        ParseACL defaultACL = new ParseACL();
        // Optionally enable public read access.
        // defaultACL.setPublicReadAccess(true);
        ParseACL.setDefaultACL(defaultACL, true);
    }

}

首先，没有必要将这两个libs行添加到Gradle文件中。这一行包含所有JAR文件。

    Vector3 newPos = Vector3.SmoothDamp(transform.position, aheadTargetPos, ref m_CurrentVelocity, damping);
    Vector3 newPos2 = new Vector3(newPos.x, newPos.y + 1, newPos.z);
    transform.position = newPos2;

现在，我通常建议您在JCenter或Maven Central中找到依赖项时尽量避免使用JAR库（如果您不确定，请查看这些库）。原因是 - 为您提供了传递依赖，版本管理需要进行一些数字更改，而不是覆盖文件等。

然后，Class not found错误可能源于使用过时版本的库。

总而言之，删除JAR文件，使用这些依赖项编译库。（上述评论中的最新版本）

compile fileTree(dir: 'libs', include: ['*.jar'])

将Parse服务器添加到现有项目中
