捕获异常的工具类

package com.example.kongqw.exceptiondemo;

import android.content.Context;
import android.support.v7.internal.app.ToolbarActionBar;
import android.util.Log;
import android.widget.Toast;

/**
* Created by kongqw on 2015/11/3.
*/
public class KqwException implements Thread.UncaughtExceptionHandler {
private static KqwException myCrashHandler;

private Context mContext;

private KqwException(Context context) {
mContext = context;
}

public static synchronized KqwException getInstance(Context context) {
if (null == myCrashHandler) {
myCrashHandler = new KqwException(context);
}
return myCrashHandler;
}

public void uncaughtException(Thread thread, Throwable throwable) {
long threadId = thread.getId();
String message = throwable.getMessage();
String localizedMessage = throwable.getLocalizedMessage();
Log.i("KqwException", "------------------------------------------------------");
Log.i("KqwException", "threadId = " + threadId);
Log.i("KqwException", "message = " + message);
Log.i("KqwException", "localizedMessage = " + localizedMessage);
Log.i("KqwException", "------------------------------------------------------");
throwable.printStackTrace();
Log.i("KqwException", "------------------------------------------------------");

// TODO 下面捕获到异常以后要做的事情，可以重启应用，获取手机信息上传到服务器等
Log.i("KqwException", "------------------应用被重启----------------");
// 重启应用
mContext.startActivity(mContext.getPackageManager().getLaunchIntentForPackage(mContext.getPackageName()));
//干掉当前的程序
android.os.Process.killProcess(android.os.Process.myPid());
}
}

使用

注册Application

<application
……
android:name=".InitApplication"
…… >
<activity
…… >
<intent-filter>
……
</intent-filter>
</activity>
</application>

package com.example.kongqw.exceptiondemo;

import android.app.Application;

/**
* Created by kongqw on 2015/11/3.
*/
public class InitApplication extends Application {

@Override
public void onCreate() {
super.onCreate();

KqwException handler = KqwException.getInstance(this);
Thread.setDefaultUncaughtExceptionHandler(handler);
}
}

测试类

package com.example.kongqw.exceptiondemo;

import android.app.Activity;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}

public void bug(View view) {
Toast.makeText(this, "程序崩溃", Toast.LENGTH_SHORT).show();
// 除数为0 导致程序崩溃
int a = 1 / 0;
}
}
