AppCompat、Vectors 和 4.1.2 的奇怪崩溃

Question

I get a very strange crash being reported when I try and run my app on Android v4.1.2 (API 16). The following error I get on older phones:

I'm using vectors with the vectorDrawables.useSupportLibrary = true setting turned on in my gradle build file. I'm referring to my images using the following code:

<ImageButton android:id="@+id/playQueueButton"
        android:layout_marginRight="20dp"
        android:layout_marginEnd="20dp"
        android:layout_height="48dp"
        android:layout_width="48dp"
        style="@style/AppTheme.Button.Flat.Inverse"
        app:srcCompat="@drawable/ic_queue_music_black_24dp"/>

My style is defined as following:

<style name="AppTheme.Button.Flat" parent="Widget.AppCompat.Button.Borderless">
    <item name="android:layout_margin">0dp</item>
    <item name="android:tint">?android:textColorPrimary</item>
    <item name="android:textColor">?android:textColorPrimary</item>
</style>

<style name="AppTheme.Button.Flat.Inverse" parent="AppTheme.Button.Flat">
    <item name="android:tint">?android:textColorPrimaryInverse</item>
    <item name="android:textColor">?android:textColorPrimaryInverse</item>
    <item name="android:background">@drawable/home_button_selector</item>
</style>

I can't find any details online about this error. I'm not sure why it's crashing.

Answer 1

@chubbsondubs seems like you can only apply tint to drawables from 5.0 and above? here's the document [Official Android document]

[1] https://developer.android.com/training/material/drawables.html

Answer 2

I got the similar error and it seemed that "?android:textColorPrimary" may not be defined in some old systems.

My Solution:
1. Define textColorPrimary in my own color.xml
2. Change "?android:textColorPrimary" to "@color/textColorPrimary"

The drawable could be tinted no matter Vector or not in my Android 4.2.2 mobile

Answer 3

So I never figured out why Android is throwing this error. After all the SDK tools should've replaced the @color reference with a proper integer from R class. So what's the heck is happening?

Turns out it didn't like the use of the tint property in the style. If removed tint and replaced my vector drawable with a vector with the right color viola it worked. So it was hard to find out if tint was supported or not on API 16, but it sounded like tint was partially "supported", but not fully on API 16.

I was using tint property before and it was working, but it was not inheriting from that AppCompat style. It only had this problem using tint + AppCompat. So this is a problem between AppCompat + tint property, and not the tint property in general.
