当我尝试在具有 android 版本 4 的平板电脑上运行我的应用程序时，它将无法正常工作并在 log cat 中出现此错误

如您所见，这个 Splash.java 非常简单，请告诉我如何使图像适合平板电脑

公共类 SplashScreen 扩展 Activity {

//how long until we go to the next activity
protected int _splashTime = 5000; 

private Thread splashTread;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    final SplashScreen sPlashScreen = this; 

    // thread for displaying the SplashScreen
    splashTread = new Thread() {
        @Override
        public void run() {
            try {
                synchronized(this){

                        //wait 5 sec
                        wait(_splashTime);
                }

            } catch(InterruptedException e) {}
            finally {
                finish();

                //start a new activity
                Intent i = new Intent();
                i.setClass(sPlashScreen, MainActivity.class);
                        startActivity(i);

                stop();
            }
        }
    };

    splashTread.start();
}

//Function that will handle the touch
@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        synchronized(splashTread){
                splashTread.notifyAll();
        }
    }
    return true;
}

}

在合适的可绘制文件夹中找不到启动画面图像。

用于 7 英寸平板电脑的 drawable-large-mdpi 或 hdpi 文件夹。

用于 10 英寸平板电脑的 drawable-xlarge-mdpi 或 hdpi 文件夹。

使用正确的图像。

并签入清单文件中的标签

<supports-screens
        android:anyDensity="true"
        android:largeScreens="true"
        android:normalScreens="true"
        android:smallScreens="true"
        android:xlargeScreens="true" />
