Application not compatible with older Android versions

I'm generating an Android application via mvn -Pandroid gluonfx:build gluonfx:package. Here are the versions from the POM:
<maven-compiler-plugin-version>3.10.1</maven-compiler-plugin-version>
<maven-surefire-plugin-version>3.0.0-M6</maven-surefire-plugin-version>
<javafx-maven-plugin-version>0.0.8</javafx-maven-plugin-version>
<gluonfx-maven-plugin-version>1.0.14</gluonfx-maven-plugin-version>
<java-version>17</java-version>
<javafx-version>18.0.1</javafx-version>
<charm-version>6.1.0</charm-version>
<attach-version>4.0.15</attach-version>
Using graalvm-svm-java17-linux-gluon-22.1.0.1-Final
The application works well on Android 8. However, when trying to install it on Android 7.0, a message pops up saying that the application is not compatible with the device. I'm not sure where the default version is specified, but following the instructions, I copied the manifest file, which was
<?xml version='1.0'?>
<manifest xmlns:android='http://schemas.android.com/apk/res/android' package='my.app.demo' android:versionCode='1' android:versionName='1.0'>
<supports-screens android:xlargeScreens="true"/>
<uses-permission android:name="android.permission.INTERNET"/>
<application android:label='MyApp' android:icon="#mipmap/ic_launcher">
<activity android:name='com.gluonhq.helloandroid.MainActivity' android:configChanges="orientation|keyboardHidden">
<intent-filter>
<category android:name='android.intent.category.LAUNCHER'/>
<action android:name='android.intent.action.MAIN'/>
</intent-filter>
</activity>
<activity android:name='com.gluonhq.helloandroid.PermissionRequestActivity'/>
</application>
</manifest>
and added a line for supporting sdk 24 (matches Android 7.0):
...
<supports-screens android:xlargeScreens="true"/>
<uses-sdk android:minSdkVersion="24" android:targetSdkVersion="24"/>
<uses-permission android:name="android.permission.INTERNET"/>
...
Then I put it in my project under src/android/AndroidManifest.xml and ran mvn -Pandroid gluonfx:build gluonfx:package again. The APK was generated successfully, but upon installation the same error message appeared.
How do I install the app on Android 7.0?

As mentioned in the comments, the device uses an ARMv7 processor, which uses a 32bit architecture. GraalVM supports only 64 bits, so the APKs produced by it will work only on devices with 64bits, like those with ARMv8.

Eclipse-no launcher activity found

I am having a problem with this.
When I run my app in the emulator, the console says that no launcher activity found when I already add one in the xml file.
Here is the console log

Try this -
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />

Android external activity fails

I'm trying to set up android multiple file chooser from https://github.com/paulasiimwe/Android-Multiple-file-Selector-Dialog.
I've added dependency to this library from my project.
Problem is app just fails when I click "run as android application".

And my code calling external activity:
import paul.arian.fileselector.FileSelectionActivity;
...
setContentView(R.layout.activity_main);
Intent intent = new Intent(getBaseContext(), FileSelectionActivity.class);
startActivityForResult(intent, 0);
...
onActivityResult is exactly same as man said in https://github.com/paulasiimwe/Android-Multiple-file-Selector-Dialog.
Could anyone help with that?

Adb Transfer Protocol Error. No such file or directory

I tried to run my android app in a emulator using intelliJ 13, and I configured the emulator to be a Nexus 4 running android 4.4.2 with ARM cpu, and I got the follow errors:
Waiting for device.
"C:\Program Files (x86)\Android\android-sdk\tools\emulator.exe" -avd MyAVD0 -netspeed full -netdelay none
Device connected: emulator-5554
Device is online: emulator-5554

Adb Transfer Protocol Error.
No such file or directory
The following is my manifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.HelloDroid"
android:versionCode="1"
android:versionName="1.0">

<application android:label="#string/app_name" android:icon="#drawable/ic_launcher">
<activity android:name=".MyActivity"
android:label="#string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
</application>
</manifest>
The emulator showed nothing on screen as well, only when I pressed hardware button to switch on the emulator and only 'android' logo showed up and stayed forever.
I built the app using Android SDK 4.4.2 api.
So the work around is to delete the MyAVD0 in C:\Users\username\.android\avd, and recreate MyAVD0 again using Android AVD Manager.

Android (Eclipse) cannot find google-play-services_lib.apk tried multiple solutions

I am creating an android application that displays a map based on the Google maps API, which should be compatible with android 2.3 API level 10.
I have tried all the solutions i could come across such as:
imported existing code into my project (checked copy to workspace and its the directory google-play-services-lib)
added the correct meta and such in my XML (see below)
I have tried setting up the emulator with several different settings
The android application runs fine, but when this page is shown is exits.

Seeing your error log, there is one solution provided in this link. Dont import google-play-services_lib APK, you should reference it on your project as an Android Library Project.

I had the same problem.
Look at project: Properties-> Java Build Path under projects remove google-play-services_lib.
Not necessary to include in build also as a project.
