}

private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {

    List<PackageInfo> packs = getPackageManager().getInstalledPackages(0);
    for(int i=0;i开发者_如何学编程<packs.size();i++) {
        PackageInfo p = packs.get(i);
        if ((!getSysPackages) && (p.versionName == null)) {

        newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
        newInfo.pname = p.packageName;
        newInfo.versionName = p.versionName;
        newInfo.versionCode = p.versionCode;
        newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
        res.add(newInfo);

Although the info you want can be retrieved using getInstalledPackages() and using PackageInfo

But as you want to share the app from one phone to another I dont think its possible atleast unless the device is rooted

C2MD is nice to send small amount of data and its fairly easy to implement. If you dont want to do that just send a sms to the other phone and have a receiver on the second mobile.

You can retrieve the information you need using the PackageManager, both ApplicationInfo and PackageInfo may be used.

private static final String TAG = "MyActivity";  
...

final PackageManager pm = getPackageManager();
final List<ApplicationInfo> installedApps = pm.getInstalledApplications(PackageManager.GET_META_DATA);

for ( ApplicationInfo app : installedApps ) {
    Log.d(TAG, "Package: " + app.packageName);
    Log.d(TAG, "Directory: " + app.sourceDir);
    Log.d(TAG, "Icon: " + app.icon);

    try {
        PackageInfo packageInfo = pm.getPackageInfo(app.packageName, PackageManager.GET_PERMISSIONS);

        Date installTime = new Date( packageInfo.firstInstallTime );
        Date updateTime = new Date( packageInfo.lastUpdateTime );

        Log.d(TAG, "Installed: " + installTime.toString());
        Log.d(TAG, "Updated: " + updateTime.toString());
        Log.d(TAG, "Version: " + packageInfo.versionCode);
        Log.d(TAG, "Name: " + packageInfo.versionName);
    }
    catch ( PackageManager.NameNotFoundException e ) {
        e.printStackTrace();
    }
}
