要獲取Android Keymaster權限,請按照以下步驟操作:
<uses-permission android:name="android.permission.USE_KEYSTORE" />
<uses-feature android:name="android.hardware.keymaster" />
import android.security.keystore.KeyProperties;
boolean isKeymasterAvailable() {
try {
KeyProperties keyProperties = new KeyProperties.Builder().setEncryptionPaddings(KeyProperties.ENCRYPTION_PADDING_NONE).build();
return KeyProperties.isKeymasterFeatureAvailable(keyProperties);
} catch (Exception e) {
return false;
}
}
import android.Manifest;
import android.content.pm.PackageManager;
import androidx.core.app.ActivityCompat;
import androidx.core.content.ContextCompat;
private static final int KEYSTORE_PERMISSION_REQUEST_CODE = 1;
private void requestKeystorePermission() {
if (ContextCompat.checkSelfPermission(this, Manifest.permission.USE_KEYSTORE) != PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.USE_KEYSTORE}, KEYSTORE_PERMISSION_REQUEST_CODE);
} else {
// Permission already granted, you can proceed with using Keymaster
}
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
if (requestCode == KEYSTORE_PERMISSION_REQUEST_CODE) {
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// Permission granted, you can proceed with using Keymaster
} else {
// Permission denied, show a message to the user
}
}
}
完成以上步驟后,您可以在應用中使用Android Keymaster API。請注意,Keymaster API僅在Android 9(API級別28)及更高版本中受支持。在使用Keymaster API之前,請確保您的應用已針對這些版本進行了適當的配置。
