java.lang.AssertionError: could not bind to KeyChainService

Question

android开发，如上报错
代码如下：
private void setKeystoreCertficate() {
new Thread() {
public void run() {
String certstr = "";
try {
X509Certificate cert = KeyChain.getCertificateChain( Settings_Basic.this, mProfile.mAlias)[0];//<-------报错行
certstr=X509Utils.getCertificateFriendlyName(cert);
} catch (Exception e) {
certstr="Could not get certificate from Keystore";
}

final String certStringCopy=certstr;
Settings_Basic.this.runOnUiThread(new Runnable() {
@Override
public void run() {
mAliasCertificate.setText(certStringCopy);
// mProfile.systemContainerCert = certStringCopy;
}
});
}
}.start();
}
报错情况：

每次运行完，第一次进入activity界面执行到如上setKeystoreCertficate()方法没问题，但是退出再进入该界面执行时就会报错如上标题，报错位置停留在已标出，这是为什么呢？求大神解答，在线等。
