public int
flags
Flags associated with the application. Any combination of {@link #FLAG_SYSTEM}, {@link #FLAG_DEBUGGABLE}, {@link #FLAG_HAS_CODE}, {@link #FLAG_PERSISTENT}, {@link #FLAG_FACTORY_TEST}, and {@link #FLAG_ALLOW_TASK_REPARENTING} {@link #FLAG_ALLOW_CLEAR_USER_DATA}.
public String
sourceDir
Full path to the location of this package.
public String
publicSourceDir
Full path to the location of the publicly available parts of this package (i.e. the resources and manifest). For non-forward-locked apps this will be the same as {@link #sourceDir).
public String[]
sharedLibraryFiles
Paths to all shared libraries this application is linked against. This field is only set if the {@link PackageManager#GET_SHARED_LIBRARY_FILES PackageManager.GET_SHARED_LIBRARY_FILES} flag was used when retrieving the structure.
public String
dataDir
Full path to a directory assigned to the package for its persistent data.
public int
uid
The kernel user-ID that has been assigned to this application; currently this is not a unique ID (multiple applications can have the same uid).
public boolean
enabled
When false, indicates that all components within this application are considered disabled, regardless of their individually set enabled status.

public java.lang.CharSequenceloadDescription(PackageManager pm)
Retrieve the textual description of the application. This will call back on the given PackageManager to load the description from the application.

param
pm A PackageManager from which the label can be loaded; usually the PackageManager from which you originally retrieved this item.
return
Returns a CharSequence containing the application's description. If there is no description, null is returned.

        if (descriptionRes != 0) {
            CharSequence label = pm.getText(packageName, descriptionRes, null);
