I try to control a GPIO Port on Android App using the Android Things Project. But when I run this app through ADB(on Android Studio), the following message is issued..
Installation failed with message INSTALL_FAILED_MISSING_SHARED_LIBRARY. It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
WARNING: Uninstalling will remove the application data!
Do you want to uninstall the existing application?
How can I resolve this problem?
Android version is Android 5.1.1(API 22) My Android App is coded according to the web site which explains the Android Things Project(https://developer.android.com/things/sdk/pio/gpio.html#managing_the_connection)
The build.gradle for app is the following.
apply plugin: 'com.android.application'
android {
compileSdkVersion 24
buildToolsVersion "24.0.3"
defaultConfig {
applicationId "kr.iges.wallpad.gpiotest"
minSdkVersion 15
targetSdkVersion 25
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:25.1.0'
provided 'com.google.android.things:androidthings:0.1-devpreview'
}
And AndroidManifest.xml is
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="kr.iges.wallpad.gpiotest">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<uses-library android:name="com.google.android.things"/>
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.IOT_LAUNCHER"/>
<category android:name="android.intent.category.DEFAULT"/>
</intent-filter>
</activity>
</application>
</manifest>
And JAVA Code is
package kr.iges.wallpad.gpiotest;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import com.google.android.things.pio.PeripheralManagerService;
import java.util.List;
public class MainActivity extends AppCompatActivity {
private static final String TAG = "GpioTest";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
PeripheralManagerService manager = new PeripheralManagerService();
List<String> portList = manager.getGpioList();
if (portList.isEmpty()) {
Log.i(TAG, "No GPIO port available on this device.");
} else {
Log.i(TAG, "List of available ports: " + portList);
}
setContentView(R.layout.activity_main);
}
}
Do you know the solution for this problem?
Thanks for your reading.
Add the things shared library entry to your app's manifest file: This worked for me. Make sure you add uses-library within the application tag only. ...
