Stetho In Action 

Known to work with: * - Some assembly required. Picasso, Fresco, Glide, ... Retrofit Ion okhttp HttpURLConnection* AndroidAsync HttpClient* Volley 

HttpURLConnection stethoMgr = new StethoURLConnectionManager(requestName); conn = url.openConnection(); stethoMgr.preConnect(conn, ...); try { conn.connect(); stethoMgr.postConnect(); } catch (IOException e) { stethoMgr.httpExchangedFailed(e); throw e; } InputStream response = stethoMgr.interpretResponseStream( conn.getInputStream()); // read response... 

▪ Adds ~60KB to an APK ▪ Initializes in ~1ms ▪ Safe in release builds, but not required Overhead 

Debug only builds dependencies { debugCompile 'com.facebook.stetho:stetho:1.1.0' compile 'com.facebook.stetho:stetho-urlconnection:1.1.0' // or debugCompile '...stetho-okhttp...' } 

Debug only builds (cont.) 

Now the fun stuf 

dumpapp ▪ Think many main(String[]) methods ▪ Built like a true CLI ▪ Simplicity as a feature 

Example: crash $ dumpapp crash kill $ dumpapp crash throw 

Example: hprof $ ./scripts/hprof_gen.sh 

Example: custom plugin
