问题 I'm trying to broadcast an adb-command to a broadcast-receiver. This would be a very simple task, but the braodcast-receiver has: android:exported="false" On the offical android.developer website, it says: If "false", the only messages the broadcast receiver can receive are those sent by components of the same application or applications with the same user ID.

问题 I'm writing a game using android ndk. I'm using picking to select objects in opengl. For that i have an offscreen framebuffer object where i render into and i use glReadPixels() to get the color from the FBO. The color then encodes the id of the clicked object. The problem is glReadPixels() does not work. It just does not read any color values. Is there anything I have to do, to make it work? GLubyte pixel[4] = {0,0,0,0}; glReadPixels(x, y , 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, (void *)pixel);

问题 How can I restrict my apk to not install on small devices, I know about the support-screens parameter but as I understand correctly , it won't work if user is installing directly from apk. 回答1: I think you can only restrict devices that can see your app in the market. If they have your apk, there's no stopping them. You can however check the resolution on startup, and display an alert or something. 来源： https://stackoverflow.com/questions/8092101/android-restricting-apk-install-for-small

问题 In the AndroidManifest file, I want to capture the BOOT_COMPLETED event when the user re-boots their device. I am adding this permission: "uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" I have seen two "intent-filters" used by others on Stackoverflow: "Intent.ACTION_BOOT_COMPLETED" and "android.intent.action.BOOT_COMPLETED" What is the preferred action string here? Please advise and explain. 回答1: Intent.ACTION_BOOT_COMPLETED == android.intent.action.BOOT_COMPLETED
