No screen mirroring on Meizu#6480

Environment

  • OS: windows
  • Scrcpy version: 3.3.3
  • Device model: Meizu M1 E
  • Android version: 7.0

Describe the bug

After launching scrcpy v3.3.3, no screen mirroring appears, and the terminal shows no error messages.

However, when I use scrcpy v1.25, everything works normally.

When I compared the code of the two versions, I found a piece of useful code.
In the fillAppInfo method of Workarounds.java.
Application app = Instrumentation.newApplication(Application.class, ctx);

So I modified the code in v3.3.3:

private static void fillAppContext() {
        try {
            Application app;
            if (Build.BRAND.equalsIgnoreCase("meizu")) {
                app = Instrumentation.newApplication(Application.class, FakeContext.get());
            } else {
                app = new Application();
                Field baseField = ContextWrapper.class.getDeclaredField("mBase");
                baseField.setAccessible(true);
                baseField.set(app, FakeContext.get());
            }

            // activityThread.mInitialApplication = app;
            Field mInitialApplicationField = ACTIVITY_THREAD_CLASS.getDeclaredField("mInitialApplication");
            mInitialApplicationField.setAccessible(true);
            mInitialApplicationField.set(ACTIVITY_THREAD, app);
        } catch (Throwable throwable) {
            // this is a workaround, so failing is not an error
            Ln.d("Could not fill app context: " + throwable.getMessage());
        }
    }

I have not tested the compatibility of this line of code, so I only added a simple condition check, but it does work for me.

I hope this can help with your compatibility work!
