App installed through android studio not shown in Launcher

android, android-gradle-plugin, android-studio

Solution

You can actually have an intent filter with `data android:host` in the launcher activity. It just needs to be a separate filter to the one containing the launcher category. The following setup makes my activity both a launcher one and browsable in order to read input parameters:

<activity android:name=".MainActivity" android:label="@string/app_name_full">
        <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.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="http"
                  android:host="www.giorgos.nl"
                  android:pathPrefix="/cv" />
            <data android:scheme="cv"
                  android:host="giorgos"/>
        </intent-filter>
</activity>

Problem

All of a sudden the app i'm working on doesn't show in the launcher. I can see it in Settings>Apps and it runs like a normal app when I start it from Android Studio. So it sounds like I'm missing: ``` <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> ``` in the manifest. Nope they're there. What else can cause this? Does build gradle mess with this possibly? This is my full manifest and build gradle file. Can anyone see something I'm missing? ``` <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.app" > <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.USE_CREDENTIALS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <uses-permission android:name="com.example.gcm.permission.C2D_MESSAGE" /> <uses-feature android:name="android.hardware.camera" /> <application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" > <meta-data android:name="com.crashlytics.ApiKey" android:value="xxxxxx" /> <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="xxxx" /> <activity android:name="com.example.app.MainActivity" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <data android:host="com.example.twitter.oauth" android:scheme="oauth" /> </intent-filter> </activity> <activity android:name="com.example.app.SigninActivity" android:label="@string/sign_in" android:screenOrientation="portrait" > </activity> <activity android:name="com.example.app.PostActivity" android:label="@string/action_new" android:screenOrientation="portrait" > </activity> <activity android:name="com.example.app.twitter.OAuthActivity" android:label="@string/action_new" android:screenOrientation="portrait" > </activity> <activity android:name="com.facebook.LoginActivity" android:theme="@android:style/Theme.Translucent.NoTitleBar" android:label="@string/app_name" /> <receiver android:name="com.example.app.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <category android:name="com.example.gcm" /> </intent-filter> </receiver> <service android:name="com.example.app.gcm.GCMIntentService" /> </application> </manifest> ``` build.gradle: ``` buildscript { repositories { maven { url 'http://download.crashlytics.com/maven' } } dependencies { classpath 'com.crashlytics.tools.gradle:crashlytics-gradle:1.+' } } apply plugin: 'com.android.application' apply plugin: 'crashlytics' repositories { maven { url 'http://download.crashlytics.com/maven' } } android { compileSdkVersion 19 buildToolsVersion '19.1.0' def versionPropsFile = file('version.properties') if (versionPropsFile.canRead()) { def Properties versionProps = new Properties() versionProps.load(new FileInputStream(versionPropsFile)) def value = 0 def runTasks = gradle.startParameter.taskNames if ('assemble' in runTasks || 'assembleRelease' in runTasks || 'aR' in runTasks) { value = 1; } def versionMajor = 1 def versionMinor = 0 def versionPatch = versionProps['VERSION_PATCH'].toInteger() + value def versionBuild = versionProps['VERSION_BUILD'].toInteger() + 1 def version_Code = versionProps['VERSION_CODE'].toInteger() + value versionProps['VERSION_PATCH'] = versionPatch.toString() versionProps['VERSION_BUILD'] = versionBuild.toString() versionProps['VERSION_CODE'] = version_Code.toString() versionProps.store(versionPropsFile.newWriter(), null) defaultConfig { versionCode version_Code versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild}) Alpha" minSdkVersion 15 targetSdkVersion 19 } } else { throw new GradleException("Could not read version.properties!") } signingConfigs { debug { storeFile file('xxx.jks') storePassword 'xxx' keyAlias 'debug' keyPassword 'xxx' } releaseKey { storeFile file('xxx.jks') storePassword 'xxx' keyAlias 'com.example.app' keyPassword 'xxx' } } buildTypes { debug { debuggable true applicationIdSuffix '.debug' runProguard false } release { runProguard false } } lintOptions{ checkReleaseBuilds false abortOnError false } } dependencies { compile files('libs/twitter4j-core-4.0.1.jar') compile files('libs/okhttp-2.0.0.jar') compile files('libs/okio-1.0.0.jar') compile 'com.android.support:support-v4:20.0.+' compile 'com.google.android.gms:play-services:+' compile 'com.android.support:appcompat-v7:20.0.+' compile project(':facebook') compile project(':parallaxViewPager') compile 'com.crashlytics.android:crashlytics:1.+' } ```
