獲取App的崩潰信息

將以下代碼放到Application的onCreate()中

private void logMessage{

    //記錄崩潰信息

    final Thread.UncaughtExceptionHandler defaultHandler = Thread.getDefaultUncaughtExceptionHandler();
    Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
        @Override
        public void uncaughtException(Thread thread, Throwable throwable) {
            //獲取崩潰時(shí)的UNIX時(shí)間戳
            long timeMillis = System.currentTimeMillis();

            //將時(shí)間戳轉(zhuǎn)換成人類能看懂的格式氢伟，建立一個(gè)String拼接器
            StringBuilder stringBuilder =new StringBuilder(new SimpleDateFormat("yyyy/MM/dd HH:mm:ss").format(new Date(timeMillis)));
            stringBuilder.append(":\n");

            //獲取錯(cuò)誤信息
            stringBuilder.append(throwable.getMessage());
            stringBuilder.append("\n");

            //獲取堆棧信息
            StringWriter sw =new StringWriter();
            PrintWriter pw =new PrintWriter(sw);
            throwable.printStackTrace(pw);
            stringBuilder.append(sw.toString());

            //這就是完整的錯(cuò)誤信息私蕾，保存到本地
            String errorLog = stringBuilder.toString();
            //將錯(cuò)誤信息寫入到文件中
            FileUtils.setAppendFile(errorLog);

            //最后處理這個(gè)崩潰，這里使用默認(rèn)的處理方式讓APP停止運(yùn)行
            defaultHandler.uncaughtException(thread, throwable);
        }
    });
}

寫入到文件的工具類

import android.os.Environment;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.PrintWriter;

public class FileUtils {
    private static final String appName = "yourAppName";
    private static File file;

    static {
        file = new File(Environment.getExternalStorageDirectory(), appName);
        if (!file.exists()) {
            file.mkdirs();
        }
        file = new File(file, "log.txt");
    }

    /**
     * 將文本追加寫入到文件
     */
    public static void setAppendFile(String value) {
        FileWriter fw;
        BufferedWriter bw;
        PrintWriter printWriter = null;
        try {
            fw = new FileWriter(file, true);
            bw = new BufferedWriter(fw);
            printWriter = new PrintWriter(bw);
            printWriter.println(value);
        } catch (Exception e) {
            e.printStackTrace();
        } finally {
            if (printWriter != null) {
                printWriter.close();
            }
        }
    }
}
