Clear Cache in Android Application programmatically

If you are looking for delete cache of your own application then simply delete your cache directory and its all done !

public static void deleteCache(Context context) {
    try {
        File dir = context.getCacheDir();
        deleteDir(dir);
    } catch (Exception e) {}
}

public static boolean deleteDir(File dir) {
    if (dir != null && dir.isDirectory()) {
        String[] children = dir.list();
        for (int i = 0; i < children.length; i++) {
            boolean success = deleteDir(new File(dir, children[i]));
            if (!success) {
                return false;
            }
        }
        return dir.delete();
    } else if(dir!= null && dir.isFile()) {
        return dir.delete();
    } else {
        return false;
    }
}

public static void deleteCache(Context context) {

try {

File dir = context.getCacheDir();

deleteDir(dir);

} catch (Exception e) {}

}

public static boolean deleteDir(File dir) {

if (dir != null && dir.isDirectory()) {

String[] children = dir.list();

for (int i = 0; i < children.length; i++) {

boolean success = deleteDir(new File(dir, children[i]));

if (!success) {

return false;

}

return dir.delete();

} else if(dir!= null && dir.isFile()) {

return dir.delete();

} else {

return false;

}

And you may require following permission to add in your manifest file in order to delete cache of other application

<uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>

1	<uses-permission android:name="android.permission.CLEAR_APP_CACHE"/>
