    private ProgressDialog mConnectionProgressDialog;
    private PlusClient mPlusClient;
    private ConnectionResult mConnectionResult;
    private Button shareButton=null;

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

        shareButton=(Button)findViewById(R.id.share_button);
        shareButton.setOnClickListener(this);

        mPlusClient = new PlusClient.Builder(this, this, this)
        .setActions("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
        .setScopes(Scopes.PLUS_LOGIN)  // recommended login scope for social features
        // .setScopes("profile")       // alternative basic login scope
        .build();
        // Progress bar to be displayed if the connection failure is not resolved.
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");

    }

    @Override
    protected void onStart() {
        super.onStart();
        mPlusClient.connect();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mPlusClient.disconnect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
        if (mConnectionProgressDialog.isShowing()) {
            // The user clicked the sign-in button already. Start to resolve
            // connection errors. Wait until onConnected() to dismiss the
            // connection dialog.
            if (result.hasResolution()) {
                try {
                    result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (SendIntentException e) {
                    mPlusClient.connect();
                }
            }
        }
        // Save the result and resolve the connection failure upon a user click.
        mConnectionResult = result;
    }

    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
            mConnectionResult = null;
            mPlusClient.connect();
        }
    }

    @Override
    public void onConnected(Bundle connectionHint) {
        String accountName = mPlusClient.getAccountName();
        Toast.makeText(this, accountName + " is connected.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onDisconnected() {
        Log.d(TAG, "disconnected");
    }

    @Override
    public void onClick(View view) {
        switch (view.getId()) {
        case R.id.share_button:
             Intent shareIntent = new PlusShare.Builder(this)
              .setType("text/plain")
              .setText("Welcome to the Google+ platform.")
              .setContentUrl(Uri.parse("https://developers.google.com/+/"))
              .getIntent();

          startActivityForResult(shareIntent, 0);
            break;
        }

    }
}

Thanks in advance

You don't need a client ID anywhere in the app - its inferred from the app packagename and the SHA1 of the signing key (which is why it asks for those in the API console). However, you don't need sign in or a key at all to do the kind of basic sharing you're doing. To test, you might want to remove all PlusClient/sign in related code until you're comfortable the PlusShare builder is creating the intent properly.

Could you make sure you're using the latest version of Google Play services (4.1) and see if you have any issues still? If so, could you check whether any more error details appear in logcat.
