2.jar package introduction

Find the sdk you need:

Introduce your own project:

Introducing jar packages: If you don't know how to introduce jar packages, please refer to this (Duniang has both): https://jingyan.baidu.com/article/e6c8503c7190b7e54f1a1893.html

3. Execute your code

1. Configure Android Manifest. xml:
   Add permissions:

  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

1. Add two Activities: Instead of creating the new two Activities, they have recently been encapsulated in the jar package

  <!-- QQjar The package is encapsulated -->
        <activity
            android:name="com.tencent.tauth.AuthActivity"
            android:launchMode="singleTask"
            android:noHistory="true">

            <intent-filter>
                <action android:name="android.intent.action.VIEW" />

                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="Here it's yours. APPID On the official website" />
            </intent-filter>
        </activity>
        <!-- QQjar The package is encapsulated -->
        <activity
            android:name="com.tencent.connect.common.AssistActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:theme="@android:style/Theme.Translucent.NoTitleBar" />

3. Code:
The code is more detailed, here note: 1. You can use this function completely after the approval of APP; 2. Initialize Tencent method; 3. Trigger login events through buttons; 4. Rewrite onActivityResult (), which is the way to get the login status after login. 5.LogUtil is my own encapsulation method, you can continue to use Log.i("""); method.

public class TextActivity extends AppCompatActivity implements View.OnClickListener {
    private Button btnQQ;
    private Button btnWX;
    private Tencent mTencent;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_text);

        initView();
        initListener();
    }

    private void initView() {
        btnQQ = findViewById(R.id.btn_login_qq);
        btnWX = findViewById(R.id.btn_login_wx);

        initQQ();
    }

    private void initQQ() { //Initialize QQ
        mTencent = Tencent.createInstance(This is yours. APPID, TextActivity.this);
    }

    private void initListener() {
        btnQQ.setOnClickListener(this);
        btnWX.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.btn_login_qq: // QQ login
                if (mTencent.isQQInstalled(TextActivity.this)) { // Determine whether QQ is installed
                    goQQLogin();
                } else {
                    Toast.makeText(this, "Please install it first. QQ", Toast.LENGTH_SHORT).show();
                }
                break;
            case R.id.btn_login_wx:
                ToastUtil.showShort(this, "Functions not yet developed,Coming soon!");
                break;
        }
    }

    /**
     * Jump QQ login
     */
    private void goQQLogin() {
        mTencent.login(this, "all", new QQLoginCallBack());
    }

    /**
     * QQ Return after login
     */
    private class QQLoginCallBack implements IUiListener {

        @Override
        public void onComplete(Object o) {
            Toast.makeText(TextActivity.this, "Log in successfully:", Toast.LENGTH_SHORT).show();
            LogUtil.i("QQ Log in successfully:" + o.toString());
        }

        @Override
        public void onError(UiError uiError) {
            Toast.makeText(TextActivity.this, "Logon failure:", Toast.LENGTH_SHORT).show();
            LogUtil.i("QQ Logon failure:" + uiError.toString());
        }

        @Override
        public void onCancel() {
            Toast.makeText(TextActivity.this, "Cancel Logon", Toast.LENGTH_SHORT).show();
            LogUtil.i("QQ Logon Cancel:");
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        Tencent.onActivityResultData(requestCode, resultCode,
                data, new QQLoginCallBack());

        if (requestCode == Constants.REQUEST_API) {
            if (resultCode == Constants.REQUEST_LOGIN) {
                Tencent.handleResultData(data, new QQLoginCallBack());
            }
        }
    }
}
