Android clear webview thread, free memory, avoid OutOfMemoryError

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.

Maybe try recycling the bitmap/image?

If that doesn't work, I suggest re-sampling it.

Strange out of memory issue while loading an image to a Bitmap object

Efficient way ever:

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());    }}

activity_web_view.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    xmlns:app="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@+id/layoutWebViewParent" >    <WebView        android:id="@+id/webView"        android:layout_width="match_parent"        android:layout_height="match_parent">    </WebView></RelativeLayout>

AndroidManifest.xml

<activity    android:name=".WebViewActivity"    android:label="@string/title_activity_web_view"    android:process="webview.kill"></activity>

Hope this will help you.
