Java Android-如何在Android中使用Arca作为bug报告器？

我试图在我的Qt Android项目中使用ARCA作为bug报告程序。我阅读了教程，在项目中添加了.JAR文件，在项目中创建了新类（ReportApp.java）

ReportApp.java：

package org.qtproject.example.myApplication;
import org.acra.*;
import org.acra.annotation.*;
import android.app.Application;

@ReportsCrashes(
    formUri = "http://********/report/reportpath.php",
    formUriBasicAuthLogin = "root",
    formUriBasicAuthPassword = "***************",
    mode = ReportingInteractionMode.TOAST,
    forceCloseDialogAfterToast = false, // optional, default false
    resToastText = R.string.crash_toast_text)
public class ReportApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ACRA.init(this);
    }
}

在AndroidManifest.xml中编辑了此行：

而不是使用

<application android:hardwareAccelerated="true" android:name="org.qtproject.qt5.android.bindings.QtApplication" android:label="@string/app_name" android:icon="@drawable/icon">

而不是

public class ReportApp extends Application

但它也不起作用

<string name="crash_toast_text">Ooooops ! I crashed, but a report has been sent to my developer to help fix the issue !</string>

<?php    
    $fileName = date('Y-m-d_H-i-s').'.txt';
    $file = fopen($fileName,'w') or die('Could not create report file: ' . $fileName);
    foreach($_POST as $key => $value) {
      $reportLine = $key." = ".$value."\n";
      fwrite($file, $reportLine) or die ('Could not write to report file ' . $reportLine);
    }
    fclose($file);
?>

public class ReportApp extends org.qtproject.qt5.android.bindings.QtApplication 

public class ReportApp extends Application
