Build an android development environment in Windows

When creating a project, the system prompts: the specified file cannot be found in proguard. cfg. 

 

Solution:

Method 1: Create a proguard. cfg file in the Android-SDK-windowstoolslib directory.

The content is as follows:

-Optimizationpasses 5
-Dontusemixedcaseclassnames
-Dontskipnonpubliclibraryclasses
-Dontpreverify
-Verbose
-Optimizations! Code/simplification/arithmetic ,! Field /*,! Class/merging /*
-Keep public class * extends Android. App. Activity
-Keep public class * extends Android. App. Application
-Keep public class * extends Android. App. Service
-Keep public class * extends Android. content. broadcastreceiver
-Keep public class * extends Android. content. contentprovider
-Keep public class com. Android. Vending. Licensing. ilicensingservice
-Keepclasseswithmembernames class *{
Native;
}
-Keepclasseswithmembernames class *{
Public (Android. content. Context, Android. util. attributeset );
}
-Keepclasseswithmembernames class *{
Public (Android. content. Context, Android. util. attributeset, INT );
}
-Keepclassmembers Enum *{
Public static ** [] values ();
Public static ** valueof (Java. Lang. String );
}
-Keep class * implements Android. OS. parcelable {
Public static final Android. OS. parcelable $ creator *;
}

 

Method 2: update the SDK through Android SDK and AVD manager.

 

About panic: cocould not open: C: \ Documents ents and Settings \ Administrator \. Android/AVD/my_avd.

Note the following two points.

1. the SDK calls the default path variable. Put the. Android folder in the Chinese directory. Therefore, it cannot be read.

2. In addition, Android-SDK-Windows cannot be placed in the Chinese directory; otherwise, errors will inevitably occur.

As long as it is not installed in the Chinese directory, it is a path problem, because the SDK environment variables are not set, the system will call the default environment variable path.

Solution
1: Create a new "system variable" in the environment variable"
Android_sdk_home = full path of Android-SDK (for example, my "D: \ Android-SDK-Windows ");
2: Modify the path of the system variable and add "% android_sdk_home %/tools;" to "..;" (if there is no "..;", pull it down and put it in front of it. ".;" Indicates the current directory. Later)

3. modify the configuration file in the eclipse installation directory: Find the following file: Eclipse \ configuration. settings \ Org. eclipse. UI. IDE. after prefs is enabled, add the environment variable you Just configured.

For example, I added: android_sdk_home = e \: \ Java \ androidsdk (note the slash format)

4: restart eclipse, re-build AVD, and run it successfully.
