我可以使用下面的代码getEncryptionState
来确定手机是否已加密。要继续,我需要验证用户输入的密码是否正确。所以我尝试了verifyEncryptionPassword()
,但效果不佳:每次调用此方法时,总是得到相同的返回值:0
。这意味着它将任何字符串作为正确的加密密码,这显然是错误的。
IMountService mountService = IMountService.Stub.asInterface(ServiceManager.getService("mount"));
boolean isEncrypted;
try {
isEncrypted = (mountService.getEncryptionState() != MountService.ENCRYPTION_STATE_NONE);
if (isEncrypted) {
int result = mountService.verifyEncryptionPassword(candidatePw);
if (result == 0) {
Log.d(TAG, "Pw verifies");
} else if (result != -2) {
Log.d(TAG, "Pw mismatch");
} else {
Log.e(TAG, "verified failed");
}
}
} catch (Exception e) {
}
如何验证加密密码?
