You have the permissions in the wrong location.  They should be outside the application tag. <manifest xmlns:android="http://schemas.android.com/apk/res/android"     package="XXXXXXXXXXXXXXXXXXXXX">         <uses-permission android:name = "andriod.permission.CALL_PHONE" />         <uses-permission android:name="android.permission.INTERNET" />         <uses-feature android:glEsVersion="0x00020000" android:required="true"/>     <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/AppTheme">         <activity android:name=".activities.MainActivity">             <intent-filter>                 <action android:name="android.intent.action.MAIN" />                 <category android:name="android.intent.category.LAUNCHER" />             </intent-filter>         </activity>         <activity android:name=".activities.ArcGISMapActivity">         </activity>     </application> </manifest>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ This documentation specified that is should be contained within the Manifest tag, not the application tag : | Android Developers  I hope this helps! ...

If you just want to use them as basemap layers you could do something like this: Basemap b = new Basemap(); b.getBaseLayers().addAll(layersCollection);         ArcGISMap arcGISMap = new ArcGISMap(b); mapView.setMap(arcGISMap);‍‍‍‍‍‍‍‍‍‍‍‍ The layersCollection object would be of type Collection<? extends Layer> so you could create a list of layer objects and then load them into the basemap to then load into the mapview. ...

I took some time today and converted the 10.2.x sample to runtime 100: This is the MBTilesLayer.java class: package com.arcgis.apps.mbtiles; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.util.Log; import com.esri.arcgisruntime.arcgisservices.LevelOfDetail; import com.esri.arcgisruntime.arcgisservices.TileInfo; import com.esri.arcgisruntime.data.TileKey; import com.esri.arcgisruntime.geometry.Envelope; import com.esri.arcgisruntime.geometry.GeometryEngine; import com.esri.arcgisruntime.geometry.Point; import com.esri.arcgisruntime.geometry.SpatialReferences; import com.esri.arcgisruntime.layers.ImageTiledLayer; import java.util.ArrayList; import java.util.List; /** * The MBTilesLayer class allows you to work with a MBTiles stored in a SQLite * database. * */ public class MBTilesLayer extends ImageTiledLayer {   private SQLiteDatabase mapDb;   private int mLevels = 0;   /**    * The constructor to instantiate MBTiles from a path on device    *    * @param path    *          path is expected to be of the form /sdcard/path/package.mbtiles    */   public static MBTilesLayer init(String path) {     SQLiteDatabase mapDb;     int mLevels = 0;     try {       mapDb = SQLiteDatabase.openDatabase(path, null, SQLiteDatabase.OPEN_READONLY);     } catch (SQLException ex) {       Log.e("MBTiles", ex.getMessage());       throw (ex);     }     // Default TMS bounds = bounds of Web Mercator projection     Envelope envWGS = new Envelope(-180.0, -85.0511, 180.0, 85.0511, SpatialReferences.getWgs84());     // See if the MBTiles DB defines their own Bounds in the metadata table     Cursor bounds = mapDb.rawQuery("SELECT value FROM metadata WHERE name = 'bounds'", null);     if (bounds.moveToFirst()) {       String bs = bounds.getString(0);       String[] ba = bs.split(",", 4);       if (ba.length == 4) {         double leftLon = Double.parseDouble(ba[0]);         double topLat = Double.parseDouble(ba[3]);         double rightLon = Double.parseDouble(ba[2]);         double bottomLat = Double.parseDouble(ba[1]);         envWGS = new Envelope(leftLon, bottomLat, rightLon, topLat, SpatialReferences.getWgs84());       }     }     Envelope envWeb = (Envelope) GeometryEngine.project(envWGS,         SpatialReferences.getWebMercator());     Point origin = new Point(envWeb.getXMin(), envWeb.getYMax(), envWeb.getSpatialReference());     Cursor maxLevelCur = mapDb.rawQuery("SELECT MAX(zoom_level) AS max_zoom FROM tiles", null);     if (maxLevelCur.moveToFirst()) {       mLevels = maxLevelCur.getInt(0);     }     Log.i("TAG", "Max levels = " + Integer.toString(mLevels));     double[] resolution = new double[mLevels];     double[] scale = new double[mLevels];     List<LevelOfDetail> lod = new ArrayList<>(mLevels);     for (int i = 0; i < mLevels; i++) {       // see the TMS spec for derivation of the level 0 scale and resolution       // For each level the resolution (in meters per pixel) doubles       resolution[i] = 156543.032 / Math.pow(2, i);       // Level 0 scale is 1:554,678,932.
