Recently, when using xposed for hook postback, a new problem appeared;
android.os.NetworkOnMainThreadException；
After Android 4.0, the HTTP request written in the main thread (that is, Activity) will report an error at runtime. This is because after Android 4.0, in order to prevent the ANR (Aplication Not Response) exception of the application, the design of Android is to prevent the network request from taking too long to cause the interface to freeze
.
I tried the first solution from the web:
1. Add code to Activity's onCreate() method
if (android.os.Build.VERSION.SDK_INT > 9) {
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
}
It still occurs, this kind of problem reports an error and has not been resolved;
2. Try to start a child thread to make a network request
new Thread(new Runnable(){
@Override
public void run() {
//请求详情
}).start();
The following is the previous scheme, directly calling new HttpHello();
