Android自定义崩溃收集器捕获java层和native层崩溃异常日志

在 Applicaiton中进行初始化崩溃收集器

public class MyApp extends Application {         @Override    public void onCreate() {             super.onCreate();        //初始化崩溃收集器        CollectCrashUtils.initColleteCrash();    }}

2.收集java层崩溃和native层崩溃

public class CollectCrashUtils {         public static void initColleteCrash() {             //初始化Handler,收集java层崩溃        MyJavaCrashHandler handler = new MyJavaCrashHandler();        Thread.setDefaultUncaughtExceptionHandler(handler);        //收集native层崩溃        File file = new File("sdcard/Crashlog");        if (!file.exists()) {                 file.mkdirs();        }        NativeBreakpad.init(file.getAbsolutePath());    }}

3.native层的崩溃收集可以使用编译好的breakpad.so。（参考 https://github.com/yinyinnie/breakpad-for-android.git）

4.java层崩溃实现Thread.UncaughtExceptionHandler接口进行收集

public class MyJavaCrashHandler implements Thread.UncaughtExceptionHandler {         @Override    public void uncaughtException(Thread t, Throwable e) {             Log.e("程序出现异常了", "Thread = " + t.getName() + "\nThrowable = " + e.getMessage());        String stackTraceInfo = getStackTraceInfo(e);        Log.e("stackTraceInfo", stackTraceInfo);        saveThrowableMessage(stackTraceInfo);    }    /**     * 获取错误的信息     *     * @param throwable     * @return     */    private String getStackTraceInfo(final Throwable throwable) {             PrintWriter pw = null;        Writer writer = new StringWriter();        try {                 pw = new PrintWriter(writer);            throwable.printStackTrace(pw);        } catch (Exception e) {                 return "";        } finally {                 if (pw != null) {                     pw.close();            }        }        return writer.toString();    }    private String logFilePath = "sdcard/Crashlog";    private void saveThrowableMessage(String errorMessage) {             if (TextUtils.isEmpty(errorMessage)) {                 return;        }        File file = new File(logFilePath);        if (!file.exists()) {                 boolean mkdirs = file.mkdirs();            if (mkdirs) {                     writeStringToFile(errorMessage, file);            }        } else {                 writeStringToFile(errorMessage, file);        }    }    private void writeStringToFile(final String errorMessage, final File file) {             new Thread(new Runnable() {                 @Override            public void run() {                     FileOutputStream outputStream = null;                try {                         ByteArrayInputStream inputStream = new ByteArrayInputStream(errorMessage.getBytes());                    outputStream = new FileOutputStream(new File(file, System.currentTimeMillis() + ".txt"));                    int len = 0;                    byte[] bytes = new byte[1024];                    while ((len = inputStream.read(bytes)) != -1) {                             outputStream.write(bytes, 0, len);                    }                    outputStream.flush();                    Log.e("程序出异常了", "写入本地文件成功：" + file.getAbsolutePath());                } catch (FileNotFoundException e) {                         e.printStackTrace();                } catch (IOException e) {                         e.printStackTrace();                } finally {                         if (outputStream != null) {                             try {                                 outputStream.close();                        } catch (IOException e) {                                 e.printStackTrace();                        }                    }                }            }        }).start();    }}
