无耻的自我推销,但我讨厌所有其他选择,特别是他们都是基于网络的。现在,我确信我需要很多工作等等,并且可能不像使用其他外部解决方案那样安全,但至少它易于使用并且有一些选择。

现在Google为此提供了SafetyNet reCAPTCHA库。
查找更多详细信息here。
以下是实现reCaptcha的步骤:
dependencies { compile 'com.google.android.gms:play-services-safetynet:15.0.1' }
使用API(来自Google文档的示例)
public void onClick(View v) {
SafetyNet.getClient(this).verifyWithRecaptcha(YOUR_API_SITE_KEY)
.addOnSuccessListener((Executor) this,
new OnSuccessListener<SafetyNetApi.RecaptchaTokenResponse>() {
@Override
public void onSuccess(SafetyNetApi.RecaptchaTokenResponse response) {
// Indicates communication with reCAPTCHA service was
// successful.
String userResponseToken = response.getTokenResult();
if (!userResponseToken.isEmpty()) {
// Validate the user response token using the
// reCAPTCHA siteverify API.
}
}
})
.addOnFailureListener((Executor) this, new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
if (e instanceof ApiException) {
// An error occurred when communicating with the
// reCAPTCHA service. Refer to the status code to
// handle the error appropriately.
ApiException apiException = (ApiException) e;
int statusCode = apiException.getStatusCode();
Log.d(TAG, "Error: " + CommonStatusCodes
.getStatusCodeString(statusCode));
} else {
// A different, unknown type of error occurred.
Log.d(TAG, "Error: " + e.getMessage());
}
}
});
}
