Check the target SDK value in the first line of your manifest. Is it android:targetSdkVersion="29"?

 

[manuelsalazar]

I have no manifest targetsdkversion line !!!

You must have something like

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)

in the manifest. It's just a warning that the targetSDKversion is for an earlier API. It will almost certainly work fine.

I have no manifest targetsdkversion line !!!

You can see the manifest from the "Project --> Manifest Editor ..." menu.

If i put targetSdkversion in manifest, compile and install in the phone the app , changes the objects like edittext , and buttoms, (the view of the objects change)

As @agraham says, the warning that you are seeing in you first post is only a warning; it is not an error. You can ignore it - there is nothing serious that needs fixing. So leave things as they are if you prefer them that way
