在2.2及以下,没有公开的API可以访问。但是,你仍然可以启动 InstalledAppDetails 活动就像 ManageApplications 一样。看here
In 2.2 and below, there is no public APIs you can access. But you can still start the InstalledAppDetails activity just as the ManageApplications does. see here
// utility method used to start sub activity
private void startApplicationDetailsActivity() {
// Create intent to start new activity
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setClass(this, InstalledAppDetails.class);
intent.putExtra(APP_PKG_NAME, mCurrentPkgName);
// start new activity to display extended information
startActivityForResult(intent, INSTALLED_APP_DETAILS);
}
结论:您可以启动应用程序信息屏幕这样的我写的:
Conclusion: you can start the "application info" screen like this i wrote:
private static final String SCHEME = "package";
private static final String APP_PKG_NAME_21 = "com.android.settings.ApplicationPkgName";
private static final String APP_PKG_NAME_22 = "pkg";
private static final String APP_DETAILS_PACKAGE_NAME = "com.android.settings";
private static final String APP_DETAILS_CLASS_NAME = "com.android.settings.InstalledAppDetails";
public static void showInstalledAppDetails(Context context, String packageName) {
Intent intent = new Intent();
final int apiLevel = Build.VERSION.SDK_INT;
if (apiLevel >= 9) { // above 2.3
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
Uri uri = Uri.fromParts(SCHEME, packageName, null);
intent.setData(uri);
} else { // below 2.3
final String appPkgName = (apiLevel == 8 ? APP_PKG_NAME_22
: APP_PKG_NAME_21);
intent.setAction(Intent.ACTION_VIEW);
intent.setClassName(APP_DETAILS_PACKAGE_NAME,
APP_DETAILS_CLASS_NAME);
intent.putExtra(appPkgName, packageName);
}
context.startActivity(intent);
}
