1. 在Application中初始化

public class BaseApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        //設(shè)置全局異常
        ExceptionCrashHandler.getInstance().init(this);
    }
}

2. 調(diào)用，并上傳錯誤信息到服務(wù)器

 @Override
    protected void initView() {
        //獲取上次崩潰的信息文件
        File crashFile = ExceptionCrashHandler.getInstance().getCrashFile();
        //把崩潰的信息上傳到服務(wù)器
        try {
            InputStreamReader fileReader = new InputStreamReader(new FileInputStream(crashFile));
            char[] buffer = new char[1024];
            int len;
            StringBuilder sb = new StringBuilder();
            while ((len = fileReader.read(buffer)) != -1) {
                sb.append(buffer, 0, len);
                sb.append("\n");
            }

            Log.e("設(shè)備信息", sb.toString());
            //上傳錯誤信息到服務(wù)器
            // ...

        } catch (Exception e) {
            e.printStackTrace();
        }
    }
