White screen at start when running debug variant

Question

Recently, I noticed running my App's debug variant of my first time - meaning installing it the first time, a white screen shows up before splash screen, which stays for quite long time ~ 15 sec on Nexus 6.

Also happens if I clear data, and run again.

At first I thought it was a side-effect of any patch, so I rolled back to the working published revision.

But the same thing occurred. Although if I install from Play, it works normally.

So, I ran a 'release' build, and voila! It was working normally. It's obviously not caused by the Application class, or any other code change, as that would happen for the release also.

It's also obviously not the same as brief white screen problem mentioned elsewhere, like this (thread): So when I applied the transparent theme to splash as suggested there, after tapping on the App, the phone screen froze, no touch worked for the same amount of time, then Splash showed.

Not getting any clue why changing to debug will cause such a huge problem. And why first run only.

Maybe this would help a bit [thread](http://stackoverflow.com/questions/36575229/android-studio-2-0-pause-white-screen-on-app-first-run?answertab=votes#tab-top) by turning off the `instant run` — Pritish Vaidya, Dec 27 '16 at 06:17

you can handle it by settings a custom theme. Do not set splash directly — Saveen, Dec 30 '16 at 17:37

It is because you're using Android studio instant run.

You can disable it like this:

Properties -> Instant Run -> uncheck 'Enable Instant Run...'

As per my experience when you working with app pls ignore this thing but when you provide a build to client/tester please make sign build and check same in your device this problem resolve. Still, i'm found the perfect solution with debugging till you may use this. ( this is only happening API 24 and later).

I don't understand what you're trying to say.. but disabling instant run resolved it. – Abu Ruqaiyah Dec 28 '16 at 11:59
Yes, my mean is Generate Signed build from the android studio it was resolved. – Arpan24x7 Dec 29 '16 at 05:40
that is an extra level of work.. whereas the problem and the solution has already been identified. – Abu Ruqaiyah Dec 30 '16 at 06:07

make a drawable like this one with name background_splash

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:drawable="@color/gray"/>

    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/ic_launcher"/>
    </item>

</layer-list>

then in styles add the style like this:

<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar">
    <item name="android:windowBackground">@drawable/background_splash</item>
</style>

then in your activity in manifest add your style

<activity
    android:name=".SplashActivity"
    android:theme="@style/SplashTheme">

If You have put android:debuggable="false"" in Manifest file Change it to

android:debuggable="true"

or Properties -> Instant Run -> uncheck 'Enable Instant Run...'
