 **JNIEnv类型实际上代表了Java环境，通过这个JNIEnv* 指针，就可以对Java端的代码进行操作。**例如，创建Java类中的对象，调用Java对象的方法，获取Java对象中的属性等等。JNIEnv的指针会被JNI传入到本地方法的实现函数中来对Java端的代码进行操作。

+# Android 修改默认输入法
+
+安卓会根据系统设置的国家地区locale选择匹配的输入法，比如当前是中国地区，匹配的输入法是中文输入法（如果系统里面安装了中文输入法的话）。
+
+项目有个奇怪的需求是无论locale是哪里，默认的输入法都要是英文输入法。
+
+那么就要修改framework层设置默认IME的代码了。
+
+我只验证了安卓4.4.4,7.1.2,8.1.0这三个版本，思路都是一样的，就是找到设置默认IME的地方，返回我们想要的IME即可。
+
+### 7.1.2 & 8.1.0
+
+frameworks/base/core/java/com/android/internal/inputmethod/InputMethodUtils.java
+
+```java
+public InputMethodListBuilder fillImes(final ArrayList<InputMethodInfo> imis,
+        final Context context, final boolean checkDefaultAttribute,
+        @Nullable final Locale locale, final boolean checkCountry,
+        final String requiredSubtypeMode) {
+    for (int i = 0; i < imis.size(); ++i) {
+        final InputMethodInfo imi = imis.get(i);
+        Log.i(TAG, "fillImes imi " + imi.toString());
+        // 【开始】添加以下代码，设置默认IME
+        if (imi.getId().equals("com.android.inputmethod.latin/.LatinIME")) {
+            mInputMethodSet.clear();
+            mInputMethodSet.add(imi);
+            Log.i(TAG, "no matter what locale, just set LatinIME as default");
+            break;
+        }
+        //【结束】
+        if (isSystemImeThatHasSubtypeOf(imi, context, checkDefaultAttribute, locale,
+                checkCountry, requiredSubtypeMode)) {
+            mInputMethodSet.add(imi);
+        }
+    }
+    return this;
+}

+            return retval;
+        }

+        if (isDefaultEnabledIme(isSystemReady, imi, context)) {
+            retval.add(imi);
+            if (imi.isAuxiliaryIme()) {
+                auxilialyImeAdded = true;

+        }
