我正在将一个应用从Eclipse迁移到Android Studio，但在尝试在API小于17的模拟器上运行应用程序时遇到了验证错误。希望能得到任何有关如何处理此类问题的指导。以下是在API 8模拟器上logcat中显示的内容：
12-27 01:48:27.189 431-431/com.zigzagworld.icjl.tanachbible W/dalvikvm: VFY: register1 v10 type 12, wanted 10
12-27 01:48:27.189 431-431/com.zigzagworld.icjl.tanachbible W/dalvikvm: VFY: rejecting opcode 0x70 at 0x005e
12-27 01:48:27.189 431-431/com.zigzagworld.icjl.tanachbible W/dalvikvm: VFY: rejected Lcom/zigzagworld/fonts/GlyphMetrics;.<init> (SSS[S)V
12-27 01:48:27.189 431-431/com.zigzagworld.icjl.tanachbible W/dalvikvm: Verifier rejected class Lcom/zigzagworld/fonts/GlyphMetrics;
这紧接着就会导致应用程序崩溃并出现
java.lang.VerifyError错误，这并不奇怪。同样的.apk文件在API 17及以上版本上运行良好。虽然在API 17及以上版本中有不同的代码路径，但无论API级别如何，GlyphMetrics类都会被使用。 （如果不同的代码路径可以影响一个类是否在加载时生成验证错误，请告诉我！）GlyphMetrics类是一个非常简单的容器，用于存储我们在应用程序中使用的自制位图字体的一些度量信息：package com.zigzagworld.fonts;
import static com.zigzagworld.fonts.Diacritics.LOWER_DIACRITIC;
import static com.zigzagworld.fonts.Diacritics.UPPER_DIACRITIC;
/**
* Represents the layout metrics for a glyph.

*/
public final class GlyphMetrics {
public static final short[] EMPTY_EXCLUSION = new short[0];
public static final short[][] EMPTY_EXCLUSIONS = { EMPTY_EXCLUSION, EMPTY_EXCLUSION };
/** The width of the glyph image, in pixels. */
public short width;
/** The height of the glyph image, in pixels. */
public short height;
/**
* The distance in pixels between the top of the glyph image and the
* baseline of the line. A positive value means that the top of the glyph
* should be above the baseline of the line; a negative value means that the
* top of the glyph should be below the baseline of the line.
*/
public short baseline;
/**
* The upper and lower axes for placement of diacriticals. Each axis is the
* distance from the left of the glyph image at which diacriticals should be
* centered. (The formatting algorithm for the font may move diacriticals
* from this position to avoid interference between glyphs.)
*/
public short[] axes;
/**

* (say) zones, the upper array has length length 2*<i>n</i>. The array has

* the same way.
*/
public short[][] zones;
public GlyphMetrics(short width, short height, short baseline, short[] layoutData) {
this.width = width;
this.height = height;
this.baseline = baseline;
axes = new short[2];
width >>= 1; // for the rest of this, we need the half-width
if (layoutData == null || layoutData.length == 0) {
axes[UPPER_DIACRITIC] = axes[LOWER_DIACRITIC] = width;
zones = EMPTY_EXCLUSIONS;
} else {
axes[UPPER_DIACRITIC] = layoutData[0];
if (layoutData.length < 2) {
axes[LOWER_DIACRITIC] = width;
} else {
axes[LOWER_DIACRITIC] = layoutData[1];
}
if (layoutData.length < 5) {
zones = EMPTY_EXCLUSIONS;
} else {
int nUpper = layoutData[2] << 1;
zones = new short[2][];
zones[UPPER_DIACRITIC] = new short[nUpper];
System.arraycopy(layoutData, 3, zones[UPPER_DIACRITIC], 0, nUpper);
int lowerStart = 3 + nUpper;
if (layoutData.length < 2 + lowerStart) {
zones[LOWER_DIACRITIC] = EMPTY_EXCLUSION;
} else {
int nLower = layoutData[lowerStart++] << 1;
zones[LOWER_DIACRITIC] = new short[nLower];
System.arraycopy(layoutData, lowerStart, zones[LOWER_DIACRITIC], 0, nLower);
}
}
}
}
}
（导入的常量
UPPER_DIACRITIC和LOWER_DIACRITIC分别是0和1。）我正在使用Android Studio 2.0 Preview 4和Gradle插件com.android.tools.build:gradle:2.0.0-alpha3以及JDK 1.7.0_80来构建这个项目。以下为.apk模块的build.gradle文件：apply plugin: 'com.android.application'

问题出现在调试构建类型中，因此此时ProGuard不涉及其中。
sourceCompatibility JavaVersion.VERSION_1_7和targetCompatibility JavaVersion.VERSION_1_7在compileOptions块中，检查库版本，重新启动IDE等）。无论如何，还是谢谢。 - Ted Hopp
