J'ai fait une modifcation dans mon code en ajoutant une seconde activité et maintenant plus rien ne fonctionne.

J'ai tenté de revenir en arrière, mais j'ai toujours le même problème.

Si quelqu'un a une idée...

Je développe pour une tablette avec le deviceSdk API26.

01/20 07:14:24: Launching 'app' on 10.1  WXGA (Tablet) API 26.
    Installation did not succeed. The application could not be installed:
    INSTALL_FAILED_OLDER_SDK
    List of apks: [0]
    'C:\Users\Moi\Desktop\EscapeGameSTW\app\build\outputs\apk\debug\app-debug.apk'
    The application's minSdkVersion is newer than the device API level.

The AndroidiManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">

    <uses-permission android:name="android.permission.WAKE_LOCK" />

    <uses-feature android:name="android.hardware.type.watch" />



    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.NoActionBar">
        <uses-library
            android:name="com.google.android.wearable"
            android:required="true" />

        <!--
               Set to true if your app is Standalone, that is, it does not require the handheld
               app to run.
        -->
        <meta-data
            android:name="com.google.android.wearable.standalone"
            android:value="true" />

        <activity
            android:name=".MainActivity"
            android:screenOrientation="landscape">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

The build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 29

    defaultConfig {
        applicationId "com.example.myapplication"
        minSdkVersion 27
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

    implementation fileTree(dir: "libs", include: ["*.jar"])
