Getting Bitmap from WebView generates OutOfMemory crash

Question

I have a custom WebView and I want to get a bitmap of its content (offscreen included). I used this code, which I got from here:

 public static Bitm         


        

Answer 1

Quick fix:-

Set android:largeHeap="true" in your AndroidManifest.xml file.

<application
    android:name="yourapplication"
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher_rounded"
    android:label="@string/app_name"
    android:largeHeap="true"
    android:roundIcon="@mipmap/ic_launcher_rounded"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

Gud luck :)

Answer 2

Okay, I've cracked this one meself. The problem indeed was in the fact that the function returned the Bitmap waay before the zooming out procedure was over, so I had to delay it.

I incorporated

Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                //bulk of my code
            }
        }, 1000);

which forced to change the structure of the function from public Bitmap to public void. Here's directly related thread. Despite some minor tweaks I still need to fix, the approach works like a charm
