First, open the simulator. Then, connect to the simulator C: \ Users \ billgates> Telnet localhost 5554 Android Console: Type 'help' for a list of commandsOK 5554 indicates the port of the simulator on the local machine.

The Android system provides telephone-related interfaces for calling, such as obtaining the phone status and mobile phone service, as well as obtaining the phone status. Therefore, you can perform different operations based on the phone status. This example mainly analyzes a code for automatically answering incoming calls. The code is written by someone else and learned together: To listen to the phone stat

I have been studying the implementation of voice calls recently. Now I have recorded my Implementation ideas here. However, this is a simple idea and a learning conclusion after Google and Baidu because of the first access to voice calls. I think a voice call system has at least four modules. These are PCM (Pulse Code Modulation) Speech collection, encoding/decoding, network transmission, and audio playback

and C + + execution performance is far above Java, such as to invoke some of the driver class interface, such as ... This article demonstrates how Java calls C + + code, which is the use of JNI.JNI layer, can be divided into the upper Jni, with the lower JNI.The JNI upper layer is implemented in Java, and the JNI lower layer is implemented in C + +.The approximate invocation relationship is this:The implementation of the JNI upper and lower laye

), ContentProvider added a new method that can be used to make cross-process method calls, as defined in the ContentProvider method:Bundle call(String method, String arg, Bundle extras)In terms of ease of use, this is not aidl so troublesome, and more extensibility, and no broadcast too dependent on the system, API 11 should be the main drawback, and other shortcomings temporarily did not find, welcome to add. BroadcastBroadcast is the simplest: t

To listen to Android calls and answer calls, you only need to write a receiver inherited from broadcastreceiverimport android in step 2. app. service; import android. content. broadcastreceiver; import android. content. context; i
