我刚刚通过http://www.androidofficer.com/2016/06/g900vvru2dpd1-android-601-marshmallow.html
中列出的手册说明将Verizion Samsung Galaxy S5(SM-G900V)更新为G900VVRU2DPD1版本当我运行下面的代码时,isHardwareDetected()返回'false'。我希望它能回归'真实'。
我所做的谷歌搜索没有以任何方式获得有关Marshmallow支持的S5指纹识别器的任何信息。
是否有人有关于支持S5指纹识别器的任何信息?
FingerprintManager manager = (FingerprintManager) getSystemService(FINGERPRINT_SERVICE);
if (manager != null) {
if (ActivityCompat.checkSelfPermission(this, permission.USE_FINGERPRINT) !=
PackageManager.PERMISSION_GRANTED) {
retVal.append(INDENT).append("Fingerprint permission was not granted")
.append(EOL);
} else {
retVal.append(INDENT).append("Fingerprint hardware detected: ")
.append(manager.isHardwareDetected()).append(EOL);
retVal.append(INDENT).append("Has Enrolled Fingerprint(s): ")
.append(manager.hasEnrolledFingerprints()).append(EOL);
}
} else {
retVal.append(INDENT).append("no FingerprintManager available").append(EOL);
}

终于解决了。看起来Android默认API无法处理某些三星设备,因此解决方案是为此问题添加三星库。
您可以在此处找到一些文档和库:http://developer.samsung.com/galaxy/pass
添加库后,您必须向清单添加新权限:
<uses-permission android:name="com.samsung.android.providers.context.permission.WRITE_USE_APP_FEATURE_SURVEY" />
最后,您可以使用此方法:
private boolean isFingerprintSupported() {
boolean isFingerprintSupported = fingerprintManager != null && fingerprintManager.isHardwareDetected();
if (!isFingerprintSupported && SsdkVendorCheck.isSamsungDevice()) {
Spass spass = new Spass();
try {
spass.initialize(context);
isFingerprintSupported = spass.isFeatureEnabled(Spass.DEVICE_FINGERPRINT);
} catch (SsdkUnsupportedException | UnsupportedOperationException e) {
// Error handling
}
}
return isFingerprintSupported;
}
