Android Introductory Source Development Basics Tutorial _android

This article describes the basics of the Android Primer tutorial. Share to everyone for your reference, specific as follows:

After downloading the Android source, the next step is to learn or develop.

Before developing, talk about some development necessary knowledge or tool, 工欲善其事 its prerequisite!

The previous "Android approach to using Eclipse for source code development" basically says development tools.

But how do we use simulators to develop?!

Of course you go to delete or add app to the simulator can not be operated as usual, take 5-10 minutes to understand if you need.

0. Compile the source code

Directly under the downloaded source root directory, execute:

SOURCE build/envsetup.sh
Make  -j4

1. Set Variable

Set the environment variables for the Android emulator so that you can use the emulator, ADB commands under any path.

Create an emulator device, here for HVGA2.3

2. Start simulator

EMULATOR-AVD hvga2.3-partition-size 256

Note: Do not write the emulator device name that you created earlier, otherwise you will get the error:

Panic:could not open:/home/mark/.android/avd/hvga2.3.ini

The terminal executes the above command to start the emulator. Then execute:

ADB remount

3. Push APK

This assumes that the gallery3d.apk push to the specified directory.

ADB-E push
/out/target/product/generic/system/app/gallery3d.apk  /system/app

4. Delete a file

Use the ADB shell and then enter the relevant directory, RM can!

5. Compile Module

If you modify a module, such as modifying the Gallery3d, then do so:

Mmm  -j4  /source2.3.7/packages/apps/gallery3d

Or:

CD Source2.3/packages/apps/gallery3d
mm  -j4

6. Compile Source code import emulator

After the module is compiled or the system compiles, you need to look at the effects of your own modifications, and you need to import the ximg file into the emulator.

After the successful compilation, in the source directory will produce an out directory, under the/out/target/product/generic can see a lot of img files,

You can import emulator by executing the following command:

CD  src/out/target/product/generic
emulator-system system.img-data userdata.img-ramdisk ramdisk.img
