Android development environment build under Linux (2)

First, the installation configuration of the JDK

Create a new folder under the Personal home folder software, under software New Java folder, for storing various Android development programs, my user name AAA, so the full directory is/home/aaa/software/java

Then copy the jdk-7-linux-x64.gz to the/home/aaa/software/java/directory, right-click Unzip, the Jdk-7-linux-x64 file will appear, right-click again to extract the jdk1.7.0 folder, 1-1:

Figure 1-1

Next configure the development environment, use the command sudo gedit/etc/environment, 1-2, add the following three lines of code, note the AAA in the code, to change to its own user name, 1-3:

Export java_home=/home/aaa/software/java/jdk1.7.0

Export JRE_HOME=/HOME/AAA/SOFTWARE/JAVA/JDK1.7.0/JRE

Exportclasspath=.: $CLASSPATH: $JAVA _home/lib: $JAVA _home/jre/lib

Figure 1-3

Edit the profile file, Sudogedit/etc/profile, add the following four lines of code, note the AAA in the code, to change to its own user name, 1-4

exportjava_home=/home/aaa/software/java/jdk1.7.0

Exportjre_home=/home/aaa/software/java/jre

Exportclasspath=.: $CLASSPATH: $JAVA _home/lib: $JAVA _home/jre/lib

Exportpath= $JAVA _home/bin: $JAVA _home/jre/bin: $PATH: $HOME/bin

Five, Android SDK Manager

After installing ADT, reboot into Eclipse, appear welcome to Android development interface, 5-1, after this interface, click Cancel or close directly;

Figure 5-1

Go to the figure 5-2 interface:

Figure 5-2

Click Window-> perferences, set the location of ANDROID-SDK, 5-3:

Using USB to connect your Android phone to your PC, confirm that your phone is enabled for USB debug mode, and then click Run->run,6-6 as shown:

Figure 6-6

If it goes well, you can see the mobile phone has entered the API Demos program interface.

If the phone fails to enter the program interface, the ADB fails to connect to the phone. You can open the terminal, enter the Platform-tools folder under the Android-sdk-linux installation directory, the specific command for CD Software/java/android-sdk-linux/platform-tools, execute. Adbdevices command, if you can see the specific device, then the computer has been connected to the phone via ADB. 6-7 is shown below:

Figure 6-7

If the ADB does not recognize devices due to multiple plug and unplug of the USB cable, a prompt for list ofdevices attached appears, 6-8, then execute the command in turn:

./adb Kill-server

./ADB Devices

List ofdevices will still be prompted after attached,6-9

You can then reseat the phone and re-execute it./ADB devices, there will be???????????? Device tips, 6-10 then execute the command in turn:

./adb Kill-server

./ADB Devices

After the general can identify the device, 6-11

List of devices attached

Figure 6-8

Figure 6-9

Figure 6-10

Figure 6-11

If you execute./adbdevices the prompt that appears is

List of devices attached

???????????? No permissions,
