1.添加依赖
implementation 'com.google.code.gson:gson:2.8.5'2.添加权限
<?xml version="1.0" encoding="utf-8"?> 3.初始化
package com.scarf.topnews;import android.app.Application;import com.scarf.topnews.utils.CrashHandler;/** * Created on 2018/11/15 13:49 * * @author Scarf Gong */public class MyApp extends Application{ @Override public void onCreate() { super.onCreate(); CrashHandler.init(getApplicationContext()); }}4.CrashHandler
package com.scarf.topnews.utils;import android.content.Context;/** * Created on 2018/11/15 14:52 * * @author Scarf Gong */public class CrashHandler { private CrashHandler() {} public static void init(Context context) { new MyExceptionHandler(context).init(); }}5.MyExceptionHandler
package com.scarf.topnews.utils;import android.content.Context;import android.os.Environment;import com.scarf.topnews.bean.LogBean;import java.io.ByteArrayInputStream;import java.io.File;import java.io.IOException;import java.io.InputStream;import java.text.DateFormat;import java.text.SimpleDateFormat;import java.util.ArrayList;import java.util.Arrays;import java.util.Date;import java.util.List;/** * Created on 2018/11/15 13:57 * * @author Scarf Gong */public class MyExceptionHandler implements Thread.UncaughtExceptionHandler { private static final String TAG = MyExceptionHandler.class.getSimpleName(); private static final String BASE_DIR = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "enterprise" + File.separator + "log"; private Context mContext; private Thread.UncaughtExceptionHandler mDefaultHandler; private DateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); MyExceptionHandler(Context context) { this.mContext = context; mDefaultHandler = Thread.getDefaultUncaughtExceptionHandler(); } public void init() { Thread.setDefaultUncaughtExceptionHandler(this); } @Override public void uncaughtException(Thread t, Throwable e) { Thread.setDefaultUncaughtExceptionHandler(null); saveCrashToFile(e); mDefaultHandler.uncaughtException(t, e); } private void saveCrashToFile(Throwable throwable) { // get the crash report StackTraceElement[] stackTraceElements = throwable.getCause().getStackTrace(); List stackTraceElementList = new ArrayList<>(Arrays.asList(stackTraceElements)); String detailMessage = throwable.getLocalizedMessage(); // get device info String versionName = DeviceUtil.getVersionName(mContext); String manufacturer = DeviceUtil.getManufacturer(); // get time String time = formatter.format(new Date()); LogBean logBean = new LogBean(); logBean.time = time; logBean.versionName = versionName; logBean.manufacturer = manufacturer; logBean.detailMessage = detailMessage; logBean.stackTraceElements = stackTraceElementList; String builder = GsonUtil.toStr(logBean); // save file InputStream inputStream = new ByteArrayInputStream(builder.getBytes()); FileUtil.saveInputStreamToFile(inputStream, BASE_DIR, time + ".txt"); try { inputStream.close(); } catch (IOException e) { e.printStackTrace(); } }} 6.工具类
6.1、DeviceUtil
package com.scarf.topnews.utils;import android.content.Context;import android.content.pm.PackageInfo;import android.content.pm.PackageManager;import android.os.Build;/** * Created on 2018/9/14 11:28 * * @author Scarf Gong */public class DeviceUtil { public static String getVersionName(Context context) { return getPackageInfo(context).versionName; } public static int getVersionCode(Context context) { return getPackageInfo(context).versionCode; } private static PackageInfo getPackageInfo(Context context) { PackageInfo pInfo = null; try { PackageManager pManager = context.getPackageManager(); pInfo = pManager.getPackageInfo(context.getPackageName(), PackageManager.GET_CONFIGURATIONS); return pInfo; } catch (Exception e) { e.printStackTrace(); } return pInfo; } public static boolean isVt320Device() { return Build.MANUFACTURER.contains("SEUIC"); } public static String getManufacturer() { return Build.MANUFACTURER; }}6.2、GsonUtil
package com.scarf.topnews.utils;import com.google.gson.Gson;/** * @author David Qin * created on 2018/11/15 */public class GsonUtil { private static Gson sGson = new Gson(); public static String toStr(Object o) { return sGson.toJson(o); } public static T toObj(String json, Class tClass) { return sGson.fromJson(json, tClass); }} 6.3、FileUtil
package com.scarf.topnews.utils;import java.io.BufferedReader;import java.io.File;import java.io.FileInputStream;import java.io.FileNotFoundException;import java.io.FileOutputStream;import java.io.IOException;import java.io.InputStream;import java.io.InputStreamReader;/** * Created on 2018/11/15 13:52 * * @author Scarf Gong */public class FileUtil { private FileUtil() { } public static boolean isFileExists(String path, String name) { File file = new File(path, name); return file.exists(); } public static void saveInputStreamToFile(InputStream inputStream, String path, String name) { File file = new File(path); if (!file.exists()) { file.mkdirs(); } file = new File(path, name); if (file.exists()) { file.delete(); } FileOutputStream fileOutputStream = null; try { file.createNewFile(); fileOutputStream = new FileOutputStream(file); StringBuilder sb = new StringBuilder(); String line; BufferedReader br = new BufferedReader(new InputStreamReader(inputStream)); while ((line = br.readLine()) != null) { sb.append(line); } String str = sb.toString(); fileOutputStream.write(str.getBytes()); } catch (IOException e) { e.printStackTrace(); } finally { if (fileOutputStream != null) { try { fileOutputStream.close(); } catch (IOException e) { e.printStackTrace(); } } } } public static FileInputStream getFileInputStreamFromPath(String path, String name) { File file = new File(path, name); if (file.exists()) { try { return new FileInputStream(file); } catch (FileNotFoundException e) { e.printStackTrace(); } } return null; }}7.LogBean
package com.scarf.topnews.bean;import java.util.List;/** * Created on 2018/11/15 14:48 * * @author Scarf Gong */public class LogBean { public String time; public String versionName; public String manufacturer; public String detailMessage; public List stackTraceElements;} 8.模拟崩溃
package com.scarf.topnews;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.TextView;public class MainActivity extends AppCompatActivity { private TextView mTextView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mTextView.setText("hello"); }}**tips：**如果没有文件，因为里不是用动态申请权限。所以需要手动去打开此项目的权限。
