Question

我正在实现Uncaught Exception Handler以跟踪我的应用程序的崩溃报告并向我发送邮件。但是我无法从我的异常处理程序发送邮件。我的Uncaught Exception Handler名称是TopExceptionHandler。我在TopExceptionHandler.java中使用此代码

public class TopExceptionHandler implements Thread.UncaughtExceptionHandler
{
private Thread.UncaughtExceptionHandler defaultUEH;

private Activity app = null;

public TopExceptionHandler(Activity app)
{
this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
this.app = app;


}



@Override
public void uncaughtException(Thread t, Throwable e)
{

    StackTraceElement[] arr = e.getStackTrace();
    String report = e.toString()+"\n\n";
    report += "--------- Stack trace ---------\n\n";
    for (int i=0; i<arr.length; i++)
    {
    report += "    "+arr[i].toString()+"\n";
    }
    report += "-------------------------------\n\n";

    // If the exception was thrown in a background thread inside
    // AsyncTask, then the actual exception can be found with getCause
    report += "--------- Cause ---------\n\n";
    Throwable cause = e.getCause();
    if(cause != null) {
    report += cause.toString() + "\n\n";
    arr = cause.getStackTrace();
    for (int i=0; i<arr.length; i++)
    {
    report += "    "+arr[i].toString()+"\n";
    }
    }
    report += "-------------------------------\n\n";

    Log.v("report", report);

    try {
    FileOutputStream trace = app.openFileOutput(
    "stack.trace", Context.MODE_PRIVATE);
    trace.write(report.getBytes());
    trace.close();
    } catch(IOException ioe) {
    // ...
    }




    sendEmail(report);




    defaultUEH.uncaughtException(t, e);


}


private void sendEmail(String report)
{

    try{
    Intent sendIntent = new Intent(Intent.ACTION_SEND);
    sendIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    String subject = "Error report";
    String body =
    "Mail this to sivaraj@onederr.com: "+
    "\n\n"+
    report+
    "\n\n"; 

    sendIntent.putExtra(Intent.EXTRA_EMAIL,
    new String[] {"sivaraj@onederr.com"});
    sendIntent.putExtra(Intent.EXTRA_TEXT, report);
    sendIntent.putExtra(Intent.EXTRA_SUBJECT, "hai");
    sendIntent.setType("message/rfc822");

    app.startActivity(Intent.createChooser(sendIntent, "Email:"));

    }
    catch(Exception e)
    {
        Log.v("sendmail", e.toString());
    }
}



@Override
protected void finalize() throws Throwable {
if (Thread.getDefaultUncaughtExceptionHandler().equals(this))
Thread.setDefaultUncaughtExceptionHandler(defaultUEH);
super.finalize();
}

}

CrashreportActivity.java

public class CrashreportActivity extends Activity {

     protected TopExceptionHandler mDamageReport = new TopExceptionHandler(this);
     String len=null;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Thread.setDefaultUncaughtExceptionHandler(new TopExceptionHandler(this));

        for(int i=0;i<len.length();i++)
        {
            Log.v("error", ""+i);
        } 
    }
}

当我尝试在uncaughtException体内做某事时，它总是失败。所以我在应用程序关闭后使用AlarmManager引发一个Activity。通过这种方式，您可以发送电子邮件，或者使用邮件内容重新激活您的应用程序，并显示错误并重新启动通知。

如何从Uncaughtexceptionhandler发送电子邮件？
