Android捕获Crash信息简单封装

集成方法：

Step 1. Add the JitPack repository to your build file

//Add it in your root build.gradle at the end of repositories:
allprojects {
        repositories {
            ...
            maven { url 'https://jitpack.io' }
        }
    }

Step 2. Add the dependency

//Add the dependency
dependencies {
    implementation 'com.github.tyhjh:CrashUtil:v1.0.1'
}

使用方法

1.在Application中初始化

CrashHander.getInstance().init(this);

2.自己实现对异常进行处理

CrashUtil.getInstance().setmSaveErro(new ISaveErro() {
    @Override
    public void saveErroMsg(Throwable throwable) {
    //异常处理
    }
});

3.或者使用提供的异常保存的本地功能

CrashUtil.getInstance().setmSaveErro(new SaveErroToSDCard(erroPath));

代码实现

Thread类中有一个getDefaultUncaughtExceptionHandler方法，可以设置系统默认异常处理器UncaughtExceptionHandler；当未捕获的异常发生的时候，系统会调用UncaughtExceptionHandler的uncaughtException方法；我们需要实现一个UncaughtExceptionHandler对象，设置为系统默认异常处理器，并在它的uncaughtException中处理异常信息。

public class CrashUtil implements Thread.UncaughtExceptionHandler {


    public static String PHONE_INFO;
    ISaveErro mSaveErro;
    Context mContext;

    private Thread.UncaughtExceptionHandler mDefultCrashHandler;

    public static CrashUtil getInstance() {
        return CrashHanderHolder.crashHander;
    }

    public void init(Context context) {
        mContext = context.getApplicationContext();
        PHONE_INFO = savePhoneInfo(mContext);
        mDefultCrashHandler = Thread.getDefaultUncaughtExceptionHandler();
        Thread.setDefaultUncaughtExceptionHandler(this);
    }

    public void setmSaveErro(ISaveErro mSaveErro) {
        this.mSaveErro = mSaveErro;
    }

    /**
     * 当系统有未捕获的异常，会触发这个方法
     *
     * @param thread
     * @param throwable
     */
    @Override
    public void uncaughtException(Thread thread, Throwable throwable) {
        //对异常进行保存处理
        if (!handleException(thread, throwable) && mDefultCrashHandler != null) {
            mDefultCrashHandler.uncaughtException(thread, throwable);
        } else {
            //这里是应该要关闭程序的，异常会导致APP出现问题，ANR黑屏等
            android.os.Process.killProcess(android.os.Process.myPid());
        }
    }

    private boolean handleException(Thread thread, Throwable throwable) {
        if (thread == null || throwable == null) {
            return false;
        }
        if (mSaveErro != null) {
            mSaveErro.saveErroMsg(throwable);
        }
        return true;
    }

    static class CrashHanderHolder {
        static CrashUtil crashHander = new CrashUtil();
    }


    // 保存手机的信息
    private String savePhoneInfo(Context context) {
        PackageManager pm = context.getPackageManager();
        PackageInfo pi = null;
        try {
            pi = pm.getPackageInfo(context.getPackageName(), PackageManager.GET_ACTIVITIES);
        } catch (PackageManager.NameNotFoundException e) {
            e.printStackTrace();
        }
        StringBuffer phoneMsg = new StringBuffer();
        phoneMsg.append("APP Version:")// APP的版本信息
                .append(pi.versionName + '_')
                .append(pi.versionCode + "\n")
                .append("OS Version:") // Android 手机版本号
                .append(Build.VERSION.RELEASE + '_')
                .append(Build.VERSION.SDK_INT + "\n")
                .append("Vendor:")// 手机制造商
                .append(Build.MANUFACTURER + "\n")
                .append("Model:")// 手机型号
                .append(Build.MODEL + "\n")
                .append("CUP ABI:" + Build.CPU_ABI + "\n");// CPU架构
        return phoneMsg.toString();
    }

}
