Android webview to call JS Error solution _android

Problem

Error WebView calling JS.

Copy Code code as follows:

Class Testjs {
......
Public Testjs () {
}

public void Save (String data) {
Webview.loadurl ("Javascript:alert (" + Data + ")");
}
......
}

Copy Code code as follows:

W/webview (2088): Java.lang.throwable:a WebView method is called on thread ' Javabridge '. All WebView methods must is called on the same thread. (Expected Looper looper (Main, Tid 1) {b3dbcb18} called on Looper (Javabridge, Tid) {B44A1AF8}, FYI main looper is Loo Per (main, Tid 1) {b3dbcb18})

Solve

Modify the Save method to:

Copy Code code as follows:

public void Save (String data) {
Webview.post (New Runnable () {
@Override
public void Run () {
Webview.loadurl ("Javascript:alert (" + Data + ")");
}
});
}

The above is the solution, is not very simple, I hope that small partners can enjoy.
