Facebook 调试工具Stetho配置入门

I decided to spend a few hours on Stetho.
Stetho is a sophisticated debug bridge for Android applications.

How to enable it
It is very simple to enable Stetho.
Just add these lines to your build.gradle:


dependencies {
    // Stetho core
    compile 'com.facebook.stetho:stetho:1.1.1'

    //If you want to add a network helper
    compile 'com.facebook.stetho:stetho-okhttp:1.1.1'
}

Then in your Application you can enable the tool just adding:

Stetho.initialize(
                    Stetho.newInitializerBuilder(this)
                            .enableDumpapp(
                                    Stetho.defaultDumperPluginsProvider(this))
                            .enableWebKitInspector(
                                    Stetho.defaultInspectorModulesProvider(this))
                            .build());

In my simple application, I have a network call with okhttp-client , a simple value in the shared preferences, and a small db with one table.
Now the last step: Run the application and just open Chrome on your pc (where the device is plugged).
In your chrome just navigate on chrome://inspect

As you can see in the image you can see 2 apps running in my device (I love Nexus4 for this kind of tests....)

Chrome
My Stetho Test App

How can I use it
Here you can open a magical world...clicking the inspect link.

First of all you can see the elements tab.

Here you can navigate in the elements inside your Activity......
Here a first surprise...clicking on the entry on the tab, the element is highlighted on the device !

The network tab.
If you work with the Chrome Developer Tools, you know it very well. Here you can see the network calls with their data.
In my app I do a simple call with okhttp

  OkHttpClient client = new OkHttpClient();
        client.networkInterceptors().add(new StethoInterceptor());

        Request request = new Request.Builder()
                .url("https://google.com")
                .build();

        client.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Request request, IOException e) {
                //do something
            }

            @Override
            public void onResponse(Response response) throws IOException {
                //do something
            }
        });

Here the tab:

The Resources tab.
In my sample app I am setting a simple value in the SharedPreferences.

 SharedPreferences.Editor editor = getSharedPreferences("TEST", MODE_PRIVATE).edit();
        editor.putString("name", "Paolo");
        editor.putInt("idName", 12);
        editor.commit();

You can check this value in the navigating in the Local Storage entry.

Also I use a simple SQLiteOpenHelper to manage a very small database with just a table.

private static final String CREATE_DATABASE = "CREATE TABLE " + TBL_USR + " ( " +
            TBL_USR_CLMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, " +
            TBL_USR_CLMN_NAME + " TEXT NOT NULL, " +
            TBL_USR_CLMN_SURNAME + " TEXT NOT NULL, " +
            TBL_USR_CLMN_CODE + " INTEGER NOT NULL DEFAULT 0 " +
            ")";

@Override
    public void onCreate(SQLiteDatabase db) {

        db.execSQL(CREATE_DATABASE);
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("+ TBL_USR_CLMN_NAME  +" , " + TBL_USR_CLMN_SURNAME +" , " + TBL_USR_CLMN_CODE  +")" + "  VALUES('PAOLO1','ROSSI1', 233432 )");
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("+ TBL_USR_CLMN_NAME  +" , " + TBL_USR_CLMN_SURNAME +" , " + TBL_USR_CLMN_CODE  +")" + "  VALUES('PAOLO2','ROSSI2', 103213 )");
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("+ TBL_USR_CLMN_NAME  +" , " + TBL_USR_CLMN_SURNAME +" , " + TBL_USR_CLMN_CODE  +")" + "  VALUES('PAOLO3','ROSSI3', 5454331 )");
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("+ TBL_USR_CLMN_NAME  +" , " + TBL_USR_CLMN_SURNAME +" , " + TBL_USR_CLMN_CODE  +")" + "  VALUES('PAOLO4','ROSSI4', 5454444 )");
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("+ TBL_USR_CLMN_NAME  +" , " + TBL_USR_CLMN_SURNAME +" , " + TBL_USR_CLMN_CODE  +")" + "  VALUES('PAOLO5','ROSSI5', 1231232 )");
        db.execSQL("INSERT INTO " + TBL_USR + " " + "("
