MoPub SDK install / usage issue

[rmloveland]

When you open the Demo App in Android Studio, it tries to build the project and fails with the following error message (atop a stack trace):

error: package com.mopub.mobileads does not exist

According to the MoPub Android repo, you need to add MoPub SDK to your build.gradle as follows:

repositories {
    jcenter()
}

dependencies {
    compile('com.mopub:mopub-sdk:4.15.0@aar') {
        transitive = true
    }
}

Since we are already pulling from the JCenter repository, we just need to add the following to our existing 'dependencies' section so it looks like this:

dependencies {
compile 'com.android.support:appcompat-v7:23.1.1'
// For aaid
compile 'com.google.android.gms:play-services-ads:9.2.1'

// From MoPub Android SDK docs
compile('com.mopub:mopub-sdk:4.15.0@aar') {
transitive = true
}

// Build from compiled libs
compile fileTree(dir: 'libs', include: ['*.jar'])
}

When re re-sync the project in Android Studio, it fails again, but differently, with the following error message:

Error:Execution failed for task ':processDebugManifest'.
> Manifest merger failed : uses-sdk:minSdkVersion 14 cannot be smaller than version 16 declared in library [com.mopub:mopub-sdk:4.15.0] /Users/rloveland/.android/build-cache/020e912c9aa50c62670f43e55499007e6bed09ee/output/AndroidManifest.xml
    Suggestion: use tools:overrideLibrary="com.mopub.mobileads" to force usage

I can "fix" the issue by editing the defaultConfig block to bump the minSdkVersion to 16 like so:

defaultConfig {
applicationId 'org.prebid.mobile.demoapp'
minSdkVersion 16 // <--- s/14/16/
targetSdkVersion 25
versionCode 1
versionName '1.0'
}

This gets the app running on the device. However, when you click MoPub > Banner, you get an error message:

ERROR: YOUR MOPUB INTEGRATION IS INCOMPLETE:
Check logcat and update your AndroidManifest.xml with the correct activities and configuration.

The instructions for updating the Android Manifest are on the MoPub Wiki, so I went to follow them.

However, when I checked the Demo App's AndroidManifest.xml it looked like all but these two were already there:

<activity android:name="com.mopub.mobileads.RewardedMraidActivity" android:configChanges="keyboardHidden|orientation|screenSize"/>
<meta-data android:name="com.google.android.gms.version"
      android:value="@integer/google_play_services_version" />

When I add these two lines to the manifest, the app stops throwing the error messages in the MoPub submenu screens but still doesn't show any ads.

Update: Just verified that everything from the above is the same, except that the MoPub ads show up fine now after going through all of the steps listed above.

This is with 0.0.2 release (commit SHA is 6c06772).

Just made a PR with the fixes that get it working for me - let me know what you think!

The fixes look good to me, merged already.
