android 捕捉app错误信息

定义MyCrashHandler类，该类实现java.lang.Thread.UncaughtExceptionHandler接口。

import java.io.PrintWriter;import java.io.StringWriter;import java.io.Writer;import java.lang.Thread.UncaughtExceptionHandler;import org.json.JSONException;import org.json.JSONObject;import android.content.Context;import android.os.Build;import android.os.Looper;public class MyCrashHandler implements UncaughtExceptionHandler {    private static MyCrashHandler myCrashHandler;    private Context context;       private MyCrashHandler() {    }    public static synchronized MyCrashHandler getInstance() {        if (myCrashHandler != null) {            return myCrashHandler;        } else {            myCrashHandler = new MyCrashHandler();            return myCrashHandler;        }    }    public void init(Context context) {        this.context = context;    }    public void uncaughtException(Thread thread, final Throwable arg1) {                    new Thread() {                @Override                public void run() {                    super.run();                    Looper.prepare();                    String errorinfo = getErrorInfo(arg1);                   //TODO  处理errorinfo                    Looper.loop();                }            }.start();    //Thread.sleep()是为了等待上面处理errorinfo的线程结束。        try {            Thread.sleep(3000);        } catch (InterruptedException e) {            e.printStackTrace();        }        android.os.Process.killProcess(android.os.Process.myPid());            }       private String getErrorInfo(Throwable arg1) {        Writer writer = new StringWriter();        PrintWriter pw = new PrintWriter(writer);        arg1.printStackTrace(pw);        pw.close();        String error = writer.toString();        return error;    }}

使用MyCrashHandler捕获异常

    MyCrashHandler handler = MyCrashHandler.getInstance();    handler.init(context.getApplicationContext());    Thread.setDefaultUncaughtExceptionHandler(handler);//将handler设置为默认
