生成异常日志

1.添加com.xzplay.crash包和里面的2个文件到src：
FrameCrashApplication.java
FrameCrashHandle.java

2.修改 AndroidManifest.xml文件：
添加SD卡读写权限
在application节点添加android:name=”com.xzplay.crash.FrameCrashApplication”

3.源码：
FrameCrashApplication.java：

package com.xzplay.crash;

import android.app.Application;

public class FrameCrashApplication extends Application {

    @Override
    public void onCreate() {

        super.onCreate();
        FrameCrashHandle crash = FrameCrashHandle.gethInstance();
        crash.Initiliaze(getApplicationContext());

    }

}

FrameCrashHandle.java：

package com.xzplay.crash;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.lang.Thread.UncaughtExceptionHandler;
import java.text.SimpleDateFormat;
import java.util.Locale;
import android.content.Context;
import android.content.pm.PackageInfo;
import android.content.pm.PackageManager;
import android.os.Environment;
import android.os.Looper;
import android.widget.Toast;

public class FrameCrashHandle implements UncaughtExceptionHandler {

    private FrameCrashHandle() {

    }

    private Context mContext;
    private static FrameCrashHandle hInstance;
    private UncaughtExceptionHandler mDefaultExceptionHandle;

    /**
     * 初始化实例
     * 
     * @param ctx
     */
    public void Initiliaze(Context ctx) {
        mContext = ctx;
        mDefaultExceptionHandle = Thread.getDefaultUncaughtExceptionHandler();
        Thread.setDefaultUncaughtExceptionHandler(this);
    }

    /**
     * 获取实例对象
     * 
     * @return
     */
    public static FrameCrashHandle gethInstance() {
        if (hInstance == null) {
            hInstance = new FrameCrashHandle();
        }
        return hInstance;
    }

    @Override
    public void uncaughtException(Thread thread, Throwable ex) {

        if (!CrashHandle(ex) && mDefaultExceptionHandle != null) {
            mDefaultExceptionHandle.uncaughtException(thread, ex);
        } else {
            try {
                Thread.sleep(1500);
            } catch (InterruptedException e) {

            }
        }
        android.os.Process.killProcess(android.os.Process.myPid());
        System.exit(110);

    }

    public static String getPackVersionInfo(Context activity) {
        try {
            PackageManager manager = activity.getPackageManager();
            PackageInfo info = manager.getPackageInfo(
                    activity.getPackageName(), 0);
            return info.versionName;
        } catch (Exception e) {
            e.printStackTrace();
            return "1.0";
        }
    }

    /**
     * 自定义处理句柄
     * 
     * @param ex
     * @return
     */
    private boolean CrashHandle(Throwable ex) {
        if (ex == null)
            return false;
        final String fileName = String.format("CityStar_Crash_%s.txt",
                System.currentTimeMillis());
        final StackTraceElement[] stack = ex.getStackTrace();
        final String msg = ex.getMessage();

        new Thread() {

            @Override
            public void run() {
                Looper.prepare();
                File f = new File(Environment.getExternalStorageDirectory(),
                        fileName);
                String s = String.format("很抱歉,程序已经崩溃,请将以下文件提交给技术人员\r\n%s",
                        f.getAbsolutePath());
                Toast.makeText(mContext, s, Toast.LENGTH_LONG).show();
                Toast.makeText(mContext, s, Toast.LENGTH_LONG).show();
                Toast.makeText(mContext, s, Toast.LENGTH_LONG).show();
                try {
                    FileOutputStream os = new FileOutputStream(f);
                    SimpleDateFormat df = new SimpleDateFormat(
                            "yyyy-MM-dd HH:mm:ss", Locale.getDefault());
                    os.write(df.format(new java.util.Date()).toString()
                            .getBytes());
                    String version = String.format("\r\nVersion:s",
                            getPackVersionInfo(mContext));
                    os.write(version.getBytes());
                    String line = String.format("\r\nCrash-> ");
                    os.write(line.getBytes());
                    os.write(msg.getBytes());
                    os.write(line.getBytes());
                    for (int i = 0; i < stack.length; i++) {
                        os.write(stack[i].toString().getBytes());
                    }
                    os.flush();
                    os.close();
                } catch (FileNotFoundException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
                }
                Looper.loop();
            }

        }.start();

        return false;

    }
}

这样一旦程序崩溃,将会在sd卡根目录生成 crash-yyyy-MM-dddd.txt文件
