Android:在运行时异常退出前显示toast

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        
        // 设置全局异常捕获
        Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread thread, Throwable throwable) {
                // 捕获到异常时显示Toast
                showToast("应用即将退出");
                
                // 延迟一段时间后退出应用
                try {
                    Thread.sleep(2000); // 延迟2秒
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                
                // 退出应用
                System.exit(0);
            }
        });
    }
    
    private void showToast(final String message) {
        // 在UI线程中显示Toast
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
            }
        });
    }
}
