Question

我相信有人发布了类似的错误，但通常我在实施Google Play游戏服务API时遇到了问题。

在onCreate（）中创建Google客户端对象时出现此日志错误：

我下载了最新版本的Google Client API，我正在使用Eclipse。

我的主要活动中的相关Google客户端代码：

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

    this.setContentView(R.layout.signin);
    this.mGoogleClient = new GoogleApiClient.Builder(this, this, this)
    .addApi(Games.API)
    .addScope(Games.SCOPE_GAMES)
    .setViewForPopups(this.findViewById(R.id.sign_in_button))
    .setGravityForPopups(Gravity.TOP | Gravity.CENTER_HORIZONTAL)
    .build();

     mResolvingError = savedInstanceState != null
                && savedInstanceState.getBoolean(STATE_RESOLVING_ERROR, false);

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

    boolean isPortrait = getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT;
    int frameBufferWidth = isPortrait ? 480 : 800;
    int frameBufferHeight = isPortrait ? 800 : 480;
    Bitmap frameBuffer = Bitmap.createBitmap(frameBufferWidth,
            frameBufferHeight, Config.RGB_565);
    display = getWindowManager().getDefaultDisplay();
    checkDimens();
    // Scaling. Good 2 Go.
    float scaleX = (float) frameBufferWidth / width;
    float scaleY = (float) frameBufferHeight / height;

    renderView = new AndroidFastRenderView(this, frameBuffer);
    graphics = new AndroidGraphics(getAssets(), frameBuffer);
    fileIO = new AndroidFileIO(this);
    audio = new AndroidAudio(this);
    input = new AndroidInput(this, renderView, scaleX, scaleY);
    screen = getInitScreen();
    lastScreen = screen;
    setContentView(renderView);
}

Answer 1

在API级别17中添加了

View.getDisplay()，即Android 4.2。您可能正在使用以前版本的设备上执行代码。您或某些库可能仅在4.2+的设备中调用getDisplay()，但设备VM在某些代码路径上看到调用，并且它不知道该方法，因此它将替换它。 / p>

但是，由于getDisplay()，您的应用不会崩溃，但是因为在第70行，您在调用Activity.requestWindowFeature后呼叫setContentView。至少这就是StackTrace所说的。

Answer 2

通过堆栈跟踪，您在设置内容this.setContentView(R.layout.signin)后尝试更改窗口功能时，应在设置内容之前调用requestWindowFeature

找不到方法view.View.getDisplay（）
