A lightweight library for determining device uniqueness and risk identification.
Create a device identifier based on basic device information.
Will remain the same after uninstalling and reinstalling or clearing app data.
🪧Attention🪧：The functions of the basic version of github are relatively limited.

}DeviceInfo contains device id, risk information and device details.
// initialization
TDRisk.init(context);
// usage
JSONObject deviceInfo = TDRisk.getBlackbox();
// Obtain deviceid and risk information through deviceInfo
String deviceID = deviceInfo.optString("device_id");
JSONObject deviceRisk = deviceInfo.optJSONObject("device_risk_label");
JSONObject deviceDetail = deviceInfo.optJSONObject("device_detail");getBlackbox method executes in the calling thread and takes time to execute.
TDRisk.Builder builder = new TDRisk.Builder();
builder.callback(new TDRiskCallback() {
@Override
public void onEvent(JSONObject deviceInfo) {
// Obtain deviceid and risk information through deviceInfo
String deviceID = deviceInfo.optString("device_id");
JSONObject deviceRisk = deviceInfo.optJSONObject("device_risk_label");
JSONObject deviceDetail = deviceInfo.optJSONObject("device_detail");
}
});
TDRisk.initWithOptions(context, builder);callback is in a sub-thread, please do not perform UI operations.

}- Basic device ID, This identifier is stable, it will remain the same even after uninstalling and reinstalling your app. But it will be different after factory reset of the device.
- Basic equipment information, which can be used for simple data analysis
- Basic risk identification ability
