Android Question Webview and API level is >=14

[Hamied Abou Hulaikah]

Hi Erel
Hi All

According to:
https://developer.android.com/guide/topics/graphics/hardware-accel.html

I have a problem with webview in many newer devices that doesn't display webview content! they display a white blank screen!

According to android doc url above, i should disable hardware acceleration, i want it done in activity level and in view level (i try in manifest file, it worked for the first activity, others no).

Activity Level:

<application android:hardwareAccelerated="true">
    <activity ... />
    <activity android:hardwareAccelerated="false" />
</application>

View Level:

myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

Please convert these code to B4A .

Thanks

Never encountered such issue.

You can use SetActivityAttribute(Main, android:hardwareAccelerated, "false") in the manifest editor.

myView.setLayerType(View.LAYER_TYPE_SOFTWARE, null);

This code, how we can use it in B4A ?

So learn how the manifest editor works and set the hardwareAccelerated attribute to false for other activties where required.
What have you added to the manifest editor so far?

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="14"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>
<application android:hardwareAccelerated="false">
</application>)

SetActivityAttribute(Main, android:hardwareAccelerated, "false")
SetActivityAttribute(activitystore, android:hardwareAccelerated, "false")

SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")

Added, but only Main activity affected!, other activities not affected, still blank!

Any suggestion?

You should set this attribute for any activity you like:

SetActivityAttribute(Activity1, android:hardwareAccelerated, "false")
SetActivityAttribute(Activity2, android:hardwareAccelerated, "false")
SetActivityAttribute(Activity3, android:hardwareAccelerated, "false")
SetActivityAttribute(Activity4, android:hardwareAccelerated, "false")
