Examples with IPackageManager android.content.pm.IPackageManager used on opensource projects

Example 1 with IPackageManager

use of android.content.pm.IPackageManager in project android_frameworks_base by ParanoidAndroid.

the class LoadedApk method initializeJavaContextClassLoader.

/**
     * Setup value for Thread.getContextClassLoader(). If the
     * package will not run in in a VM with other packages, we set
     * the Java context ClassLoader to the
     * PackageInfo.getClassLoader value. However, if this VM can
     * contain multiple packages, we intead set the Java context
     * ClassLoader to a proxy that will warn about the use of Java
     * context ClassLoaders and then fall through to use the
     * system ClassLoader.
     *
     * <p> Note that this is similar to but not the same as the
     * android.content.Context.getClassLoader(). While both
     * context class loaders are typically set to the
     * PathClassLoader used to load the package archive in the
     * single application per VM case, a single Android process
     * may contain several Contexts executing on one thread with
     * their own logical ClassLoaders while the Java context
     * ClassLoader is a thread local. This is why in the case when
     * we have multiple packages per VM we do not set the Java
     * context ClassLoader to an arbitrary but instead warn the
     * user to set their own if we detect that they are using a
     * Java library that expects it to be set.
