Android应用捕获全局异常自定义处理

[2016-06-30]最新的全局异常处理DRCrashHandler已经集成在DR_support_lib库中

具体请看: https://coding.net/u/wrcold520/p/DR_support_lib/git/tree/master

[2016-06-28] 1 增加log4j的支持
[2016-06-28] 2 增加全局异常处理（可自定义程序崩溃提示消息，自定义发送错误报告到服务器）
[2016-06-28] 3 增加两种应用退出方法：① appExit，结束掉所有Acitivity的生命周期，正常退出；② appKill，结束掉所有Acitivity的生命周期，杀掉程序进程后退出。
[2016-06-29] 4 增加透明状态栏和导航栏（默认开启，蓝色背景）

在Android程序中，我们通常会在可能发生错误的地方加上try {} catch (Exception e) {}语句来捕获异常，但是，我们无法保证程序就一定不会出错，比如，你玩Android游戏的过程中经常会碰到黑屏或者直接退出的情况，那么这些异常就应该是没有被捕获到（一般获取到都会提示用户错误，并提示用户是否将错误上传至服务器），那么现在我们来看下如何捕获全局异常，然后自己处理。

1、新建DRCrashHandler.java（这是一个抽象类，我放在了DR_supprot_lib库中，以便以后再写应用程序的时候直接使用，里面用到了一些变量是DRConstants类中的，这是一个常量类，用来定义常用的常量的）

     */
    public void setDRCrashFilePath(String mDRCrashFilePath) {
        this.mDRCrashFilePath = mDRCrashFilePath;
    }

}

2、新建DRApplication.java（抽象类，里面用到了Log4j，上一篇有讲到如果在Android中集成Log4j，这里在Application中使用DRLogHelper来初始化log4j）

package cn.dr.lib.app;

import java.io.File;
import java.util.LinkedList;
import java.util.List;

import org.apache.log4j.Logger;

import android.app.Activity;
import android.app.Application;
import cn.dr.lib.log.DRLogHelper;
import cn.dr.lib.ui.DRAcitivity;

/**
 * DarkRanger的Application
 *
 * @author DarkRanger
 *
 */
public abstract class DRApplication extends Application {

    // 当前类的log
    private static Logger log;

    // Activity列表
    private List<DRAcitivity> mActivityList = new LinkedList<DRAcitivity>();

    // drLog实例
    public DRLogHelper mDRLogHelper = DRLogHelper.getInstance();

    // 全局异常处理类的实例
    public DRCrashHandler mDRCrashHandler = new DRCrashHandler() {

        @Override
        public void initParams() {

        }

        @Override
        public void sendToServer(File logFile, File crashFile) {

        }

    };

    @Override
    public void onCreate() {

        super.onCreate();

        // 1、初始化DRLog参数
        initDRLogHelperParam();

        // 2、初始化DRLog
        initDRLogHelper();

        // 3、初始化全局异常处理类
        initCrashHandler();
    }

    /**
     * 1、初始化DRLog参数，如： <br/>
     *
     * {@link DRApplication#getDrlog()} DRLog drLog = getDrlog(); <br/>
     * {@link DRLogHelper#setLog4jFilePath(String)}
     * drLog.setLog4jFilePath(Constants.LOG4J_FILE_PATH); <br/>
     * {@link DRLogHelper#setType(cn.dr.lib.log.DRLogHelper.LogType)}
     * drLog.setType(LogType.TYPE_LOG4J); <br/>
     *
     * 只有在子类中完成initDRLogParam参数设置以后才能使用log
     */
    protected abstract void initDRLogHelperParam();

    /**
     * 2、初始化DRLog
     */
    private void initDRLogHelper() {
        getDrLogHelper().init();

        log = Logger.getLogger(DRApplication.class);
    }

    /**
     * 3、初始化CrashHandler
     */
    private void initCrashHandler() {
        log.trace("DRApplication: initCrashHandler()");

        // 3.1
        setHandler();

        // 3.2
        getDRCrashHandler().init(this);
    }

    /**
     *
     * 3.1 调用以下方法为mCrashHandler设置实例<br/>
     * <br/>
     *
     * {@link #setCrashHandler(DRCrashHandler)}
     */
    public abstract void setHandler();

    /**
     * 获取DRLog单例
     *
     * @return
     */
    public DRLogHelper getDrLogHelper() {
        return mDRLogHelper;
    }

    public DRCrashHandler getDRCrashHandler() {
        return mDRCrashHandler;
    }

    public void setDRCrashHandler(DRCrashHandler mCrashHandler) {
        this.mDRCrashHandler = mCrashHandler;
    }

    /**
     * 添加activity到App的mActivityList
     *
     * @param activity
     */
    public void addActivity(DRAcitivity activity) {
        this.mActivityList.add(activity);
    }

    /**
     * 遍历mActivityList，结束每一个activity的声明周期
     */
    private void finishActivityList() {
        for (Activity activity : mActivityList) {
            activity.finish();
        }
    }

    @Override
    public void onTerminate() {
        log.trace("DRApplication: onTerminate()");

        super.onTerminate();
        appExit();
    }

    /**
     * 完全退出程序
     */
    public void appExit() {
        log.trace("DRApplication: appExit()");

        finishActivityList();
        // 正常退出
        System.exit(0);
    }

    /**
     * 出现异常杀掉进程
     */
    public void appKill() {
        log.trace("DRApplication: appKill()");

        finishActivityList();
        android.os.Process.killProcess(android.os.Process.myPid());
        System.exit(1);
    }

}

3、

首先要说明的是：前面两个类我已经集成在DR_supprot_lib库中，在新的应用程序中只需要继承这两个类，分类初始化一些参数即可。

写个App程序测试：

3.1 新建MyCrashHandler.java继承DRCrashHandler，复写两个抽象方法initParams()和sendToServer()

package cn.darkranger.test;

import java.io.File;

import org.apache.log4j.Logger;

import android.os.Environment;
import cn.dr.lib.app.DRCrashHandler;

public class MyCrashHandler extends DRCrashHandler {
    private static final Logger log = Logger.getLogger(MyCrashHandler.class);

    String crashFilePath = Environment.getExternalStorageDirectory() + File.separator + "MyApp" + File.separator
            + "Crash.txt";

    @Override
    public void initParams() {
        // 设置程序崩溃提示信息
        setDRTipMsg("this is my msg - -");
        // 设置程序崩溃的文件位置
        setDRCrashFilePath(crashFilePath);
    }

    @Override
    protected void sendToServer(File logFile, File crashFile) {
        log.info("logFile: " + logFile + "; crashFile: " + "\naction:sendToServer - -");
        // 这里要写上传错误信息到服务器的代码，暂时不写，看需求，自己实现
    }

}

3.2 新建MyApplication.java继承DRApplication，复写两个抽象方法initDRLogHelperParam()和setHandler()

package cn.darkranger.test;

import java.io.File;

import org.apache.log4j.Logger;

import android.os.Environment;
import cn.dr.lib.app.DRCrashHandler;

public class MyCrashHandler extends DRCrashHandler {
    private static final Logger log = Logger.getLogger(MyCrashHandler.class);

    String crashFilePath = Environment.getExternalStorageDirectory() + File.separator + "MyApp" + File.separator
            + "Crash.txt";

    @Override
    public void initParams() {
        // 设置程序崩溃提示信息
        setDRTipMsg("this is my msg - -");
        // 设置程序崩溃的文件位置
        setDRCrashFilePath(crashFilePath);
    }

    @Override
    protected void sendToServer(File logFile, File crashFile) {
        log.info("logFile: " + logFile + "; crashFile: " + "\naction:sendToServer - -");
        // 这里要写上传错误信息到服务器的代码，暂时不写，看需求，自己实现
    }

}

3.3 新建MainActivity，这里暂时不继承DRActivity，继承AppCompatActivity，两个testview，点击第一个，调用DRApplication的退出，点击第二个，抛出异常，我们自己捕获。

package cn.darkranger.test;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;public class MainActivity extends AppCompatActivity {

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

        TextView exitTv = (TextView) findViewById(R.id.id_exit);
        exitTv.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                ((MyApplication) getApplication()).appExit();
            }
        });

        TextView testCrashTv = (TextView) findViewById(R.id.id_testCrash);
        testCrashTv.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                throw new IllegalArgumentException("this is an IllegalArgumentException! ");
            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
}

3.4 更改AndroidManifest.xml（添加读写文件的权限，设置application为：cn.darkranger.test.MyApplication）

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cn.darkranger.test"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="21" />

    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

    <application
        android:name="cn.darkranger.test.MyApplication"
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

测试：
