这是我打开应用程序崩溃时的启动画面活动。但是在某些手机中，该应用程序不会崩溃。我不知道是什么问题，请帮我解决

您没有关闭进度条，因此它显示泄漏的窗口消息。
在完成活动之前，请关闭进度条对话框。

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.progress_circle_activity);
progressBar = new ProgressDialog(ProgressCircleActivity.this);
progressBar.setMessage("Please wait ...");
progressBar.setCancelable(true);
progressBar.setProgressStyle(ProgressDialog.STYLE_SPINNER);
progressBar.setProgress(0);
progressBar.setMax(100);
progressBar.show();
new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(3*1000);
Intent i=new Intent(ProgressCircleActivity.this,PhoneNumberLogin.class);
startActivity(i);//dismiss the progressdialog
progressBar.dismiss();
//Remove activity
finish();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}).start();
}
