I am displaying a fairly large image in a webview so that the pinch-to-zoom functions and other conveniences for viewing are already available.
It displays correctly the
Okay, so the conclusion to this issue was that the String buffer could not be predetermined or properly cleared at these file sizes.
In this case the image was pulled from a server as a string, manipulated as a string and finally displayed as an image.
Whether displayed as an ImageView or as a Webview, it did not matter, the app would crash once a string buffer became full (which it would not clear no matter how much stuff I freed or set to null), This was an encryption effort.
but Finally just settled with storing the images in the app's assets folder.
WebViewActivity.java
public class WebViewActivity extends AppCompatActivity {
private WebView mWebView;
private RelativeLayout mWebViewParent;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mWebViewParent = (RelativeLayout) findViewById(R.id.layoutWebViewParent);
mWebView = (WebView)findViewById(R.id.webView);
// Other stuff
}
@Override
protected void onDestroy() {
super.onDestroy();
destroyWebView();
}
private void destroyWebView() {
mWebViewParent.removeAllViews();
if(mWebView != null) {
mWebView.clearHistory();
mWebView.clearCache(true);
mWebView.loadUrl("about:blank");
mWebView.freeMemory();
mWebView.pauseTimers();
mWebView = null;
}
android.os.Process.killProcess(android.os.Process.myPid());
}
}

Hope this will help you.
Maybe try recycling the bitmap/image?
If that doesn't work, I suggest re-sampling it.
