Android代码通过包名调用系统卸载程序

/** * 卸载指定包名的应用 * @param packageName */public boolean uninstall(String packageName) {    boolean b = checkApplication(packageName);    Logger.d(TAG, "Test:check:"+b);    if (b) {        Uri packageURI = Uri.parse("package:".concat(packageName));        Intent intent = new Intent(Intent.ACTION_DELETE);        intent.setData(packageURI);        startActivity(intent);        return true;    }    return false;}/** * 判断该包名的应用是否安装 * * @param packageName * @return */private boolean checkApplication(String packageName) {    Logger.d(TAG, "Test,run");    if (packageName == null || "".equals(packageName)) {        return false;    }    try {        getPackageManager().getApplicationInfo(packageName,                PackageManager.MATCH_UNINSTALLED_PACKAGES);        return true;    } catch (PackageManager.NameNotFoundException e) {        Logger.e(TAG, "Test:"+e.toString());    }    return false;}
