java.lang.IllegalStateException: System services not available to Activities before onCreate()

这是我运行测试应用程序时遇到的错误。
public class Testnew extends ActivityInstrumentationTestCase2<DeviceIntelligence>{
public Testnew() {
super("com.android.deviceintelligence.activity", DeviceIntelligence.class);
}
Context mContext;
private DeviceIntelligence mdevint;
protected void setUp() throws Exception {
super.setUp();
mdevint = new DeviceIntelligence();
}
protected void tearDown() throws Exception {
super.tearDown();
}
public void testEmailAccounts() {
mdevint.emailAccounts();
Assert.assertNotNull(mdevint);
}
}
这是我的测试应用程序代码。 emailaccounts（）是我的活动类中的一个方法，它在类中定义了它。我需要检查方法是否正常工作或所有可能的输入。
public void emailAccounts() {
Log.d(TAG, "inside emailaccount");
Account[] accounts = AccountManager.get(this).getAccounts();
int size = ead.selectAll().size();
List<String> dbAcc = ead.select();
Log.d(TAG, "dbAcc: " + dbAcc.toString());
Log.d(TAG, "size: " + dbAcc.size() + " " + "length: " + accounts.length);
if (accounts.length != 0) {
if (size == 0) {
for (Account eAccounts : accounts) {
ead.insert(eAccounts.name, eAccounts.type);
}
} else {
for (Account acc : accounts) {
if (!dbAcc.contains(acc.name + acc.type)) {
ead.insert(acc.name, acc.type);
;
}
}
}
}
这是我的emailaccounts（）方法。请帮我提前解决问题。谢谢。

答案 0 :(得分：0)
在调用emailAccounts()之前，您必须使用AITC2#getActivity()创建活动。
public void testEmailAccounts() {
DeviceIntelligence activity = getActivity();
activity.emailAccounts();
// ...
}
顺便说一句，你绝不应该尝试使用new创建活动，就像new DeviceIntelligence()一样。
