How to make my APK compatible with any device?

I'm doing an APP with android studio. I've finished it, I've made it Build correct but I tried to install it in a "Huawei P8 Lite" and it tells me that it is not compatible with the device.

What part of the code is what makes it incompatible?

This is the file "AndroidManifest.xml"

'

<uses-sdk
    android:minSdkVersion="15"
    android:targetSdkVersion="22" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WAKE_LOCK"/>

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

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/MyMaterialTheme"
    android:name="com.mp3player.searchonline.App" >
    <!--This meta-data tag is required to use Google Play Services.-->
    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
    <activity
        android:name="com.google.android.gms.ads.AdActivity"
        android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
    <activity
        android:name="com.mp3player.searchonline.MainActivity"
        android:label="@string/app_name"
        android:windowSoftInputMode="adjustNothing" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="com.mp3player.searchonline.PlayerActivity"
        android:label="@string/app_name"
        android:theme="@style/MyDialogTheme" >
        </activity>
</application>
