Question

我正在尝试在对话框中启动Google地方选择器，但它并没有启动。以下是我正在使用的代码：

bool rsa_gen_keys() {
    int ret = 0;
    BIO *bio_private = NULL;
    BIO *bio_public = NULL;
    int bits = 4096;

    EVP_PKEY_CTX *ctx;
    EVP_PKEY *pkey = NULL;

    // Get the context
    ctx = EVP_PKEY_CTX_new_id(EVP_PKEY_RSA, NULL);
    if (!ctx)
        goto cleanup;

    // init keygen
    if (EVP_PKEY_keygen_init(ctx) <= 0)
        goto cleanup;

    // set the bit size 
    if (EVP_PKEY_CTX_set_rsa_keygen_bits(ctx, bits) <= 0)
    goto cleanup;

    /* Generate key */
    if (EVP_PKEY_keygen(ctx, &pkey) <= 0)
        goto cleanup;


    // write rsa private key to file
    bio_private = BIO_new_file("private_new.pem", "w+");
    ret = PEM_write_bio_PrivateKey(bio_private, pkey, NULL, NULL, 0, NULL, NULL);
    if (ret != 1) {
        goto cleanup;
    }
    BIO_flush(bio_private);

    // write rsa public key to file
    bio_public = BIO_new_file("public_new.pem", "w+");

    //ret = PEM_write_bio_RSAPublicKey(bio_public, rsa);
    ret = PEM_write_bio_PUBKEY(bio_public, pkey);
    if (ret != 1) {
        goto cleanup;
    }
    BIO_flush(bio_public);


cleanup:
    if(bio_private) BIO_free_all(bio_private);
    if(bio_public) BIO_free_all(bio_public);
    if(pkey) EVP_PKEY_free(pkey);

    return ret;
}

这是我的清单文件：

package com.settings.android.elisea;

public class AddContact extends AppCompatActivity {

    private Button location;
    int PLACE_PICKER_REQUEST = 1;

    // Configure sign-in to request the user's ID, email address, and basic

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.addaction);
        location = (Button) findViewById(R.id.location);
        location.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();

                Intent intent;
                try {
                    intent = builder.build(AddContact.this);
                    startActivityForResult(intent, PLACE_PICKER_REQUEST);
                } catch (GooglePlayServicesRepairableException e) {
                    e.printStackTrace();
                } catch (GooglePlayServicesNotAvailableException e) {
                    e.printStackTrace();
                }
            }
        });
    }


    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            final Place place = PlacePicker.getPlace(this, data);
            final CharSequence name = place.getName();
            final String address = place.getAddress() + "";
            String attributions = (String) place.getAttributions();
            if (attributions == null) {
                attributions = "";
            }
            location.setText(address);
            location.setText(address);
            location.setText(address);
        }

    }

}

我已经在谷歌凭证中创建了一个API，但我不认为这是问题，因为它没有启动也没有显示任何违规行为。
