折腾：
【未解决】rcsjta的core出错：FATAL EXCEPTION main android.os.FileUriExposedException file exposed beyond app through Intent.getData()
期间，调试core期间，点击保存，遇到另外的错误：

代码是：
src/com/gsma/rcs/utils/ContactUtil.java
/**
* Creates a ContactId from a validated phone number
*
* @param phoneNumber the validated phone number
* @return the Contact Identifier
*/
public static ContactId createContactIdFromValidatedData(PhoneNumber phoneNumber) {
synchronized (ContactUtil.class) {
if (mContactUtil == null) {
mContactUtil = com.gsma.services.rcs.contact.ContactUtil.getInstance(AndroidFactory
.getApplicationContext());
}
}
try {
return mContactUtil.formatContact(phoneNumber.getNumber());
} catch (RcsPermissionDeniedException e) {
/*
* This exception cannot occur since PhoneNumber can only be instantiated for valid
* numbers.
*/
String errorMessage = "Phone number '" + phoneNumber
+ "' cannot be converted into contactId!";
throw new IllegalStateException(errorMessage, e);
}
}看起来是：
获取手机号失败了？
那去找找代码逻辑。
number是前面传入的
src/com/gsma/rcs/provisioning/local/ProvisioningHelper.java
public void saveContactIdEditText(int resViewTextId, String settingsKey) {
EditText txt = (EditText) mRootView.findViewById(resViewTextId);
String text = txt.getText().toString();
ContactUtil.PhoneNumber number = ContactUtil.getValidPhoneNumberFromUri(text);
if (number == null) {
txt.setText("");
}
mRcsSettings.writeContactId(settingsKey,
"".equals(text) ? null : ContactUtil.createContactIdFromValidatedData(number));
}去研究看看第一就：
EditText txt = (EditText) mRootView.findViewById(resViewTextId);
此处返回的值如何
然后此处运行不到断点，无法调试。
再去想其他办法
再去找找相关代码逻辑
后记：
【未解决】通过调试rcsjta中core的入口Provisioning去寻找服务启动的逻辑
期间，可以调试到一些断点了
包括 点击保存后，最终触发运行到了上面的
com.gsma.rcs.provisioning.local.Provisioning.onOptionsItemSelected
的部分，所以继续调试看看
【记录】调试rcsjta的core的apk点击保存按钮触发Provisioning的onOptionsItemSelected相关代码调用逻辑
