I installed Android Studio 3.1.3
I installed all Sdk
But he does not know a whole series of public classes like findviewbyid
The next problem is that I've added a series of library to the project but gets the error
I'm taking two pictures. I'm having trouble !!!!

Truly this is my SDK project information

compileSdkVersion 28
buildToolsVersion '27.0.3'
useLibrary 'org.apache.http.legacy'
defaultConfig {
    minSdkVersion 22
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

Thank you for guiding me what to do

Hello sir. I am quite new with android studio.
I have built the project without error.
Also have sync the gradle file with the project successfully.

But when I try to run the Android Studio project, it shows error.
It says that there is no APK file build for the project even though I have build the APK for the project
It also cannot find ID for the project
what should I do?

Please use URLEncoder.encode when you put data to http get request.
Without this your app can crash when you put special char or space.
