                        startActivity(i);
                        //Remove activity
                        finish();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }

这是我的splashScreenActivity，当我打开应用程序时，该应用程序崩溃了。但在某些手机中，该应用程序没有崩溃。我不知道问题是什么，请帮我解决

您没有关闭进度条，因此它显示了泄漏的窗口消息。
在完成 Activity 之前，请关闭进度栏对话框。

@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();
    }
