Intercepts hardware key events
Even if the input method window does not have a clear focus, it first receives the hardware key events and can choose whether to use or forward them to the application. For example, during text orchestration, you can use the arrow keys to navigate in the candidate area of the input UI. You can also capture the rollback key to eliminate any window popped up from the input method window.
Override the onkeydown () and onkey
For Android commands, select a few frequently used records.
1. view the Android version list
Command:

2. Create a simulator based on the version number.
Command:

The textures used to cache the glyphs is quite large, so when other applications require more memory, they may be recycled by the system. When the user hides the current application, the system sends a message to notify the application to release as much memory as possible. In most cases, the application will destroy the largest textures cache. On the Andorid device, all the textures caches except the first created (1024x512 by default) are considered as large ones.
When no cache has sp

Call and send text messages on the simulator. You can also use the emulator control of the ADT plug-in of eclipse on the command line. The specific method is as follows.
Command line:
Assume that the port number of the simulator you are currently enabling (on the title bar of the simulator) is 5554.
1. Open the command line and enter Telnet localhost 5554 and press Enter. The following prompt is displayed, indicating that you have successfully connec
The ADB shell is often used during the development of Android applications, where a simple summary of the general commands is made.The content includes DOS, Linux, Shell three blocks (obtained through access to books and web data).1.

In the Android application development, we will use a variety of code debugging; In fact, after the development of Android, we may encounter some random problems, such as high CPU, memory leaks and so on, we can not easily debug the code, we need a system log, etc., Below I grasp the work encountered several commonly used commands and methods for everyone to demo
In Android application development, we will use various types of code debugging. In fact, after Android development, we may encounter some random problems, such as high cpu and memory leakage, we cannot perform simple code debugging. We need a system log and so on. Below I will explain some common commands and methods I have encountered in my work.

The Input Method Editor (IME) is a control that allows users to input text. Android provides an extensible Input Method framework that allows applications to provide users with additional input methods, such as soft keyboard or voice input. Once these input methods are installed, you can select the ime they want from the system settings, and this setting is valid

Although visual feedback is usually the fastest way to provide users with information, this requires users to focus on the device. When a user cannot view a device, other communication methods are required. Android provides powerful Text-to-Speech and TTS APIs. This allows developers to add

For Android development, debugging of text messages and phone calls was not completed at the beginning.ProgramPut it on your phone for debugging. Several hundred text messages will be sent in a few days. Fortunately, I have 200 text packets, or I will lose money.
After time, I went online and found information about

1: Android SMS sending can be simulated in the simulator.
For example, if the ID of the first simulator is 5554,
Run cmd
Telnet local host 5554
Enter help to see many functional commands used in simulators.
GSM call 134343434 // call the current simulator command
SMS send 15555218135 hello, this is a message // is a short message sent to the current Simulator
