平台
RK3288 + Android 7.1
需求
修改系统源码, 通过Intent附带参数, 支持自动点击安装下一步, 调用代码
Intent install = new Intent(Intent.ACTION_VIEW);
install.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
File apkFile = new File(Environment.getExternalStorageDirectory() + "/download/" + "app.apk";
install.putExtra("confirm", true);
install.setDataAndType(Uri.fromFile(apkFile)), "application/vnd.android.package-archive");
startActivity(install)
补丁
