OPPO崩溃问题解决

OPPO崩溃问题解决

在APM上监控到一个高频cash，如下

崩溃线程
FinalizerWatchdogDaemon

Caused by: java.util.concurrent.TimeoutException: android.content.res.AssetManager$AssetInputStream.finalize() timed out after 10 seconds
    at android.content.res.AssetManager$AssetInputStream.close(AssetManager.java:606)

    at java.lang.Daemons$FinalizerDaemon.run(Daemons.java:177)

主线程

解决方案：

 private void fixOPPOVersionCash(){
 		//需要修复的版本号
        String[] versionPre ={"6.0.1","5.1.1","5.1"};
        String version  = DeviceUtils.getSystemVersion();
        BestLog.d("DeviceUtils.getSystemVersion()="+version);

        if(!Arrays.asList(versionPre).contains(version)){
            return;
        }

        String deviceModel = Utils.getDeviceModel();
        BestLog.d("Utils.getDeviceModel()="+deviceModel);
        if(!TextUtils.isEmpty(deviceModel)){
            if(deviceModel.contains("OPPO")){
                try {
                	//停止该进程
                    Class clazz = Class.forName("java.lang.Daemons$FinalizerWatchdogDaemon");
                    Method method = clazz.getSuperclass().getDeclaredMethod("stop");
                    method.setAccessible(true);
                    Field field = clazz.getDeclaredField("INSTANCE");
                    field.setAccessible(true);
                    method.invoke(field.get(null));
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }
    }
