我想以编程方式在Android中获取应用程序崩溃信息，而无需使用第三方应用程序或jars（例如bugsense等）

Question

I have a webview based android application I want to get the crash report and store it into a text file but i am unable to find any programmatic native solution anywhere. I have read this article but I am unable to use it. I have no code because I dont know where to start

Answer 1

The best way to handle crash logs is creating an UncaughtExceptionHandler and handling it as per your requirement. Create a BaseActivity class and extend all the Activities with that and put this code stuff in the BaseActivity class.

private Thread.UncaughtExceptionHandler handleAppCrash = 
                                     new Thread.UncaughtExceptionHandler() {
    @Override
    public void uncaughtException(Thread thread, Throwable ex) {
        Log.e("error", ex.toString());
        //send email here
    }
};

Then just enable is inside onCreate() method of your BaseActivity by using

Thread.setDefaultUncaughtExceptionHandler(handleAppCrash);

Answer 2

I am catching un-handled exceptions by using this in my activity's onCreate():

mUEHandler = new Thread.UncaughtExceptionHandler() {

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

                PrintWriter pw = new PrintWriter(new OutputStreamWriter(
                        openFileOutput(DMP_FILENAME, 0)));
                e.printStackTrace(pw);
                pw.flush();
                pw.close();
            } catch (FileNotFoundException e1) {
                // do nothing
            }
            BaseActivity.this.finish();
        }
    };

    Thread.setDefaultUncaughtExceptionHandler(mUEHandler);

This writes every unhandled exception in your app that happened on your activity to text file. Then you can analyze it.

为什么不记录Log.e（“ tag”，“ msg”）之类的所有内容，否则检查logcat的崩溃情况
